Hi People.

Since yesterday my engine has been making a very weird squeeking noise, i 1st thought it might be the fan belt lose so took a look at it as it was stiff as a board, since then its got worse, louder and now it sounds like somethings actually tapping really fast, it only happens when i put my foot on accelerator, soon as i take it off its perfect again, also i can put my foot on accelerator really slowy and build up some speed and cant hear anything, the noise sounds like its coming from the right hand side of my engine where spark plugs are. im really worried as i only brought it couple weeks ago.

Some1 please help or advise.

its a 94 p38. 4.6.

The tapping sounds like your typical , slightly worn V8 sticky hydraulic tappet, nothing to really worry about if its just one, is your oil pressure light working?? does it have an oil pressure guage??, just on the off chance the pump is on its way out although this would manifest as more of a rattle than a tappety noise, take a quick look at your bottom pulley whilst the engine is running...is it running true or is it wobbling (ie keyway about to give out and a squeaking but tight fan belt.) sorry cant be of more help but diagnosing a squeak over the net is not the most scientific of games.

Cheers Steve

hi,
thanks for the quick reply,
just called guy salmon and they said straight away its 1 of the Tappets, said its only Ã‚Â£8 to buy the tappet, then they might change the cam (Ã‚Â£217) and do oil change and filters and Gaskets (Ã‚Â£100) and then with the labour it'll all add up to Ã‚Â£700....im so shocked at that price for a Ã‚Â£8 part? does the cam need changing? is this only a maindealer job etc?

No mate its not just a main dealer job

Any independent land rover spacialist will be able to do the job

you do not say mileage of the engine

try an oil and filter change first as this is cheap and MAY fix it

VeryRandyRange · « **Reply #4 on:** February 12, 2007, 10:18:42 »

sorry, mileage is 124k.
my brother has his own garage and said he could do it and change all tapets rather then the 1 and all in all about Ã‚Â£250, but 1st he told me to get some red ex oil additive for the tappets as it might just be 1 sticky tappet.
fingers crossed!!!

im stil very worried tho!

If nowt else, give Andys Landys a call in Cov - (he's just by Morrisons on the A46 - 024 7644 4041) and ask them to have a listen. It doesn't sound like a tappet (that squeaking intrigues me), but i'm happy to be corrected on that.

Has anything recently changed do you know (parts, oils etc)?

Good luck and keep us informed!

Cheers

A tappet noise would come from the top of the engine wouldn't it? though at that mileage it's worth looking at them anyway. Also check the condition of the engine mounts, it could be the fan catching if the mounts have sagged, this would explain why it comes and goes with the throttle.

VeryRandyRange · « **Reply #7 on:** February 12, 2007, 12:40:49 »

im not sure when things were changed, the receipts etc i got with the car dnt have any for last service etc, the plugs look newish tho. ive called a few places and being told to :

drop the old oil, add flush for 30 mins, drop that out, change oil filter, then put new oil in and additive and see what happens for a couple of days, thing is with me working til 5 every night who's gonna do this for me.

i can get all the above tonight and is this an easy job which i can do myself? not too handy with cars unless they rs turbo's or impreza's.

with the noise like that am i stil safe driving the car around?

Range Rover Blues · « **Reply #8 on:** February 12, 2007, 12:53:31 »

It's easy but I always make a mess. You need a container that can catch about 10 litres. not that there's quite that much in there. Drain plug is on LHS of sump, behind the axle, filter alongside steering box.

You will need about 5 litres of flushing oil to get oil pressure back up and be caeful as you might move some sludge around from a safe place to somewhere you wouldn't want it.

Have a look into the oil filler, is it full of black gunge?

VeryRandyRange · « **Reply #9 on:** February 12, 2007, 12:55:37 »

what happens if i just put the additive on top of the oil in there now, basically not changing anything, just topping it up?

VeryRandyRange · « **Reply #10 on:** February 13, 2007, 08:34:12 »

ARGH!!!
driving home yesterday, was on the way to the auto shop to get the flush and the additive, by the time i got to the shop (20 miles), the noise had completley gone, drove over over to work (10 miles) and just got around the corner and the noise is back, worse then ever and soooo loud that people at work even heard me coming.
now what????

Skibum346 · « **Reply #11 on:** February 13, 2007, 08:41:31 »

I'm no expert, but if you like I can pop over Wednesday evening to see if I can illuminate any. I've serviced my own vehicles and have a basic understanding of what goesd on in the lump up front.

PM me your details if you'd like me to come over.

Other than that, get it to a garage that understands RRC's.

Not being funny chaps but could it be a slightly blowing cylinder head gasket/ exhaust manifold gasket,i.e the squeak then the tapping noise,a friend of mine had a scorpio that had the same sort of symptoms and his turned out to be the manifold gasket

Does it pop and fluff on the over run ??

VeryRandyRange · « **Reply #13 on:** February 14, 2007, 08:30:51 »

some1 else did say to me it may be the inlet manifold or something like that, there is a chap coming to see the car at 9.30am so i will let u no what he diagnoses.

VeryRandyRange · « **Reply #14 on:** February 14, 2007, 09:33:44 »

guys its the exhaust manifold thats cracked.

where can i get 1 from asap..

VeryRandyRange · « **Reply #15 on:** February 14, 2007, 12:25:49 »

change of plan, took the manifold out, its perfect, turns out the head gasket is seriously leaking some oil and thats what the problem is,

NEW HEADGASKET...Gutted...

is this a big expensive job. its only 1 side that needs doing.

Range Rover Blues · « **Reply #16 on:** February 14, 2007, 13:14:53 »

I'd suggest the heads need a tickle too then (light skim), do both sides so it stays balanced. Gaskets around Ã‚Â£40, not a five minute job but you can easily do it if you have the right tools and a good manual. Refit with composite gaskets not the 'tin' (actually aluminium) ones as these are more reliable. If you don't get the heads skimmed definitely use composites, they are more tolerant of warped heads too.

Are you sure this is where the noise is coming from... never heard of a leaking cylinder head causing a squeel.

Do you still need me to pop over tonight...?

the manifold and plugs atc have all been taken off the car in my work carpark so cant drive the car home. so the car wont be in when u come later, thanks so much for your help though, sorry for messing u around.

well the head on there wasnt firmly screwed down and when he took manifold off he showed me where the oil was coming from in the headgasket and where the loose gasket was hitting the manifold and making the tapping noise.

also on the manifold 1 of the bolts had snapped and this was loose as wel.

the oil cap has gone creamy as wel.

VeryRandyRange · « **Reply #20 on:** February 14, 2007, 15:24:22 »

i found prices for the headgasket sets at around Ã‚Â£40, any idea of how much total cost wil be, i only want to do the 1 side.

Range Rover Blues · « **Reply #21 on:** February 14, 2007, 18:12:02 »

Err, about Ã‚Â£40 then

I paid Ã‚Â£40 for a mate-of-a-mate to skim both heads.

If you carefully recover your antifreeze (I syphon it out of the header tank into a bottle) then you can filter and re-use it.

I really recomend doing both heads :!:

If you have the time then strip the head and fit new valve stem selas, re-lap the valves in. The valves will have small black circles on the seating face, this is ok but lap them in until these go and you get a continuous grey ring. If the black circles are big, like pits and have a rough crater-like bottom, replace the valve.

If you can be bothered I also take the time to grind any sharp adges from the inlet/exhaust tract in the head (but maybe that's just me).

drmike · « **Reply #22 on:** February 14, 2007, 21:45:20 »

From the sound of it you'd be best getting your garage owning brother to do this - or have I got muddled somewhere? Changing the head gasket isn't that hard but it doesn't sound like you've had lots of experience and don't have that much time.

I'm surprised the gasket set is Ã‚Â£40, I'm sure I didn't pay that much.

You really need a RR expert to look at it though as someone suggested a local independent will be the best bet for that as there may be a number of issues lurking there.

On the other hand one quick gasket later and all may be well!

Mike

VeryRandyRange · « **Reply #23 on:** February 15, 2007, 08:35:50 »

hi guys
thanks for all your input.
my brother is going to skim the heads and replace both gaskets as well as all other gaskets, new manifold bolts etc and oil liquid material for Ã‚Â£210.
i dnt think thats to harsh a price. He's supplying everything.

drmike · « **Reply #24 on:** February 15, 2007, 09:00:07 »

Cripes he's your brother can't you blackmail him with baby photos or something :lol:

Can he check the block and everything at the same time as aren't these bigger V8 supposed to suffer from porous blocks?

Mike

VeryRandyRange · « **Reply #25 on:** February 15, 2007, 09:02:51 »

haha if i showed him baby pics he'd prob put the price up!!!
i dnt actually know what he'll be doing or what it'll involve, as long as the car is running fine etc i trust him. i might get him to change the tappets, cam and manifold at same time to save from future risks.

Range Rover Blues · « **Reply #26 on:** February 15, 2007, 19:07:20 »

Ã‚Â£210 including parts, I'd let him do it, want to do mine at the same time

I wouldn't worry about porous block syndrome, it's actually a cracking of the aluminium around the liner more often than not (though I have seen it appear on the galsket surface) but it's not such a problem on the 3.9 as the 4.6.

Garth · « **Reply #27 on:** February 19, 2007, 23:37:55 »

Just changed BOTH head gaskets skimmed BOTH heads renewd ALL Tappets

Heads skimmed x 2 Ã‚Â£70

Top end gasket set Ã‚Â£54 (bearmark)

Hydrolic tappets x 16 Ã‚Â£48 (LR)

Did all work (except head skimming) myself so sounds a good price
