Transit 2.5Di engine

[matthew]

Hello all

It's on topic 'cos the engine is fitted to my S2a 109".

Last Sunday I ground to a halt, finally today I've had time to investigate and as suspected the cam belt has snapped, luckily it just seems to have broken a couple of rocker arms and bent a couple of push rods. I've got the head off and there doesn't seem to be any marks on the pistons or valves.

Does anybody have any information on these engines?

Like how to get everything lined up for the new belt?
Torque settings?
Tightening order for the head bolts?

Whilst I'm at it, it has a pipe between the exhaust manifold and inlet through a valve type thing, like most modern'ish diesels I've seen. What purpose does this serve? Will it improve or be worse if I blank this off?

When the belt goes on a transit engine it tends to just bend pushrods and maybe snap a rocker or two. To lock the engine in the timing position - there's a hole just above the starter motor - 11mm drill bit in there and rotate the engine until it sinks into a corresponding hole in the flywheel.
Belt cover off and there's a hole on the cam sprocket (6mm), which lines up with a hole in the casing behind it. Same with the inj pump.
The pipe is exhaust gas recycling.

Someone once told me the DI ran a non interfearance valve train (verry odd for a diesel) - I guess they were lieing then!

The exhaust thing is the EGR valve, its to improve imissions slightly at some speeds.  The engine will run atleast as well without it and as you motor is far to old to need to worry about imissions its completely pointless having it - more to go wrong!

:roll: This is one from the depths of history, nearly 4 years ago.

For the benefit of anyone else that may have a similar problem in the future, as far as I can remember the only damage was to the rockers and push rods.
