Title: sounds like a steam train with the oil cap off
Post by: muddysteve on October 31, 2006, 13:39:23: its a 200tdi and seems to be using a fair bit of oil
no oil in coolant or vice versa but chuffs like a gooden with the oil filler cap off

head gasket or somethin more expensive?

Chuffs out of the oil filler cap when cap is removed??

You've got a blown head gasket most likely between No three and four cylinders at the pushrod part.

Like to put ten bob on it ?? LOL

A simple easy if time consuming job.

Post by: muddysteve on October 31, 2006, 13:53:42: puffs out a bit of blue smoke when been idling for a while but other than that ok

i did find a bit of oil in the airfilter so its definatly over pressurising the lube system

Post by: bigfatsi on October 31, 2006, 13:55:59: Either way,a compression test will help. If one or two cylinders are low then you've probably got a head gasket gone. If they are all low but increase with a small squirt of oil in the cylinder the rings. *Works on petrol - don't know about putting oil in a diesel cylinder!*

thats what i want to hear, i can do time consuming at the monent but not expensive :shock:

next question is paddocks list 3 different head gaskets for the 200tdi, any ideas?

Post by: Porny on October 31, 2006, 15:09:47: If you look underneath glowplugs 3 and 4 (i.e. the ones closest to the bulkhead) you should find a section of the head gasket sticking out slightly (between two protruding sections of the head casting)... have a look to see how many holes are punched in it - then you know which one to order.

The different number of holes highlight the thickness of the head gasket.

And before people start waffling on :roll: :wink: ...

Gasket thickness isn't anything to do with the head and compression ratio.

Different gasket thicknesses are for different piston protrusion... i.e. deck heights... the protrusion of the piston from the top of the cylinder block.
(though this is related to compression ratio in a way)

Taken from the workshop manual (for a 300tdi, but process for a 200tdi is the same):

Quote

New cylinder head gasket should be same thickness as the original. If, however, cylinder head, pistons or crankshaft have been replaced, it will be necessary to check piston stand proud in order to determine the correct thickness of gasket.

1. Position a magnetic base DTI to cylinder block top face adjacent to number 1 cylinder bore.

2. Position stylus of gauge to cylinder block top face on edge of number 1 cylinder bore; zero gauge.

3. Rotate crankshaft in a clockwise direction until numbers 1 and 4 pistons are at TDC.

4. Position stylus of DTI gauge near edge of piston crown, measure and record number 1 piston stand proud. Measurement must be taken at front and rear of piston and highest protrusion figure recorded.

5. Repeat above procedures for remaining pistons.

6. From all of the readings obtained, determine highest protrusion figure and select the appropriate cylinder head gasket. Protrusion 0.50 to 0.60 mm - select gasket with 1 identification hole. Protrusion 0.61 to 0.70 mm - select gasket with 2 identification holes. Protrusion 0.71 to 0.80 mm - select gasket with 3 identification holes. Protrusion 0.81 to 0.90 mm - select gasket with 0 identification holes. NOTE: Identification holes are located on the edge of the gasket.

7. Remove DTI.

8. Rotate crankshaft in a clockwise direction until all pistons are half-way up cylinder bores.

Post by: Miniman on October 31, 2006, 17:45:45: Has it just started like all of a sudden or has it been getting worse and worse if so how quickly...... Also take off the air filter and listen to see how it sounds. It may sound like its popping on just one cylinder if so there is a poss that you have a broken ring or a hole in a piston.....Its very uncommon in diesels but we have had one...... Go on tell us started to do it all of a sudden or progressivley

Why do you need to fit the thinnest gasket/fit a different thickness gasket if you have the head skimmed??? :roll: :?

Post by: Devon-Rover on October 31, 2006, 22:01:46: Sounds like rings to me. and the bores might have become glazed as well. letting oil seep into the bores.

but its a tdi hu knows :lol:
wip head off and then find a nice healthy score down no 1 pot :cry:

Post by: mmgemini on November 01, 2006, 09:30:23: How many miles has that engine done ??
90,000 or 180,000 if so it's time for a head gasket.

I've already put money on a head gasket. LOL

Post by: muddysteve on November 01, 2006, 15:58:32: 180000 how did u guess?

it was the HG there wasnt a lot of gasket left between no4 cylinder and no8 pushrod

ran a straight edge over the head and seem pretty flat pistons and bores look brand new once i cleaned the carbon off

just waiting for a mate to arrive with his torque wrench so we can nip the head up re-fit the rocker gear and fill it with coolant, then it'll be time for a test run

Thank you Steve.

My 200Tdi did the same at 92,000 miles.
In exactly the same place.No 4 to pushrod.
