Type 4 Oil Leak - another thread sorry!

So me and the mrs were out in the van today and after I saw some white smoke I thought I should check the engine.

Went round the back and saw oil on the bumpers and the tailgate and p*ssing out around the offside tinware. Gutted!

Engine has been fine but I topped up the oil this morning. Had to get the AA to bring us back and will be getting the van up tomorrow and get the tinware off to see where its coming from. Have rebuilt the engine with new seals so really surprised....

Any ideas on where to start - Im hoping it will be an easy fix without dropping the engine....

Let me know

 

That side and it could be from all sorts of places due to the fan. Mine did the same and it was the little rubber tube the dipstick goes through between the block and the fan housing. Astonishing amount of oil came out, same white smoke as oil dripped onto the heat exchangers and its well worth checking

 

Fuel pump loose? Thermostat cable roller bolt still in place, if thermostat not fitted?? Hole isn't blind, so oil gets siphoned out with the air flow over it!!

 

You need to do the tedious task of jet washing the engine clean then run the engine up and watch where the oil comes from. Could be rocker covers, pushrods tubes, oil filler tube/dipstick tube. Could also be coming from the opposite side you think.

 

Got under there today and the cork gasket around the rocker is leaking and so are the pushrod tubes at the head end....hopefully spotted it just in time.

So im gonna call GSF and see if they have the gaskets/seals needed.

I'm going to replace all 16 pushrod seals and the cork gaskets on the rocker. But how do i get a good seal? Ive read that most seals are done with just oil but i want something a bit more reliable - Permatex i'm thinking?

Its a Type 4 so hopefully can do in situ - Ive got the van on ramp stands and can get at the rocker covers easy - any other tips before I dive in?

 

seems to be 2 thread running, the push rod seals need a bit of lubrication on them and slight rotation to seat correctly - don't force them, make sure you locate the push rods right - they don't self centre and have fun with the annoying wire thing that holds the tubes.

 

Hi Rikyroo - yeah sorry started as a general discussion about my travel plans turned into an SOS in mech and tech.What do you mean by 'locate them right'?

Also I just rung GSF and they only have the black seals - are they any good or should I hold out for the green ones for the engine case side?

Cheers for all the help

 

The push rods have to sit in the "cups" in the end you can't see in the engine, don't just pop them in and think they will self centre.
the black ones are poo i bought about 4 green and the rest black, the green are still dry the black are leaking - if you can only source a few then green to heads and black to the cooler end is best but seriously mine have been in maybe 2 years and leaking for the last 12 months again!

 

Ok so ive reinstalled the pushrods and new seals but now the bloody thing wont start. Could it be a timing issue....

Have turned the engine over by hand and the pushrods and rockers seem to be right...what else can it be as it was running perfevct before we started...

 

Did you have to adust any of the rockers by more than half a turn?

 

I didnt adjust the rockers at all whilst they were off the van hence I was just expecting her to fire up.

Im wondering if the pushrods are located correctly all round - they look like their in OK.

Does the pushrod/rockers always need to be adjusted after this kind of job - there doesnt seem to be any play in the tappets at all, as is the valve clearances are a s tight as they can be.

 

I bet you've not got them centred in the lifters... type 4s don't self centre, you need to lift them with a screwdriver

So essentially your valves are staying open!!

 

@Paulweeding - I think they're in the rockers - they look as if they are sat nicely in the cups. Are the 'lifters' inside the engine?

If so is there a way to tell if they are centred or it just a case of when you know, you know? You know?

 

i said earlier check they were located in the bottom end

 

Lifters as in cam followers

Rockers are rockers

And yes, the pushrods need to be located properly in the cam followers

 

i knew what i meant!

 

Stateside Tuning have the ones you need.

 

Oops too late...! Good luck with whatever you fitted.
