Althogh I should have known better, I just checked the torque of the other caps. Kicking myself now, but was elated to find something so obvious at the time, plus was using my mates business with a hoist so was on a bit of a time crunch. The plan now is to rip the sump off again, look at all the oth...

Could be, but had no choice to use another cap, bearing fit and fit to block is good with the replacement cap. It's now a chicken and egg situation, did the broken bolt cause the vibration in the first place, or did the vibration/knock case the bolt to break. Vibration is less than before but def th...

Hi on a recent trip back from France the AAZ engine in my T25 developed an engine vibration/knock. Luckily we made it home and the problem didn't get any worse. Last week I decided to remove the sump, and found what i thought was the problem, No 4 main bearing cap had snapped a bolt and was laying i...

Check the turbo oil feed pipe, they fracture and spray oil about

Have you checked that the scuttle panel is not full of leaves and blocking up the drain holes?
I have seen several cars now that have had this problem, rain water starts to work its way into the footwell and onto electrics all because the two little drains under the bonnet are blocked.

Possibly CV joint loose

Iv'e got a used recon hella starter motor that I took off a van last year that you can have for £40 posted if you want.
Just pm me.

Hi As rob says above, but that is worse case. I would check all of the fuel hoses as well, especially the injector bleed off pipes as it sounds like it's getting air into the fuel system to me, also check or replace the fuel filter and the plastic valve on top of it. sounds like the power steering b...

There is a screw on the top of the blowoff valve, you could try screwing that in to the max and take it out for anothe drive just in case the spring inside has gone weak. Also on the turbo there is a little canister with a small alen bolt and lock nut, you could try undoing that a few turns, it adju...

there you go.
I take it that it was all quiet up to that point?

If you are just changing the turbo there is only one gasket, and it is from the turbo to the down pipe, no gasket between the turbo and exhaust manifold beleive it or not, just go carefull or you could end up with two turbo's with snapped bolts in them. Have you tryed blocking off the blow off valve...

Sorry forgot to say, I wouldn't try to swap the wastegate's, just try another turbo on there, but only if it's not to much hassel for you.

Changing the turbo isn't to hard, but the bolts will probobly be rusted/seized and can be a bit of a pig. The turbo bolts are 12 point I think so not standard type of bolt, and are two diferent lengths from memory. I used loads of heat on mine as i have got use of accetaline. Brickwerks sell them ne...

One other thing to remember as well, you won't be able to replicate it on your drive way, the engine will have to be under load at maximum boost.

Thanks, Chris

Always hard to describe a noise, but it still sounds like the same problem that I had. If the van has not lost any power then the likely cause is probobly the turbo wasegate seized shut. from what I can remember its like a little valve that is supposed to open at a pre set pressure. If it is seized ...
