Power loss

Post by Rattling » Wed Nov 20, 2019 3:25 pm

Hi having recently had a new exhaust manifold fitted and everything seemingly ok ,I now have a loss of power when I put the car under load ,I can hear the turbo spinning but no extra power boost ,if I ease the accelerator a little bit it will give me a slight improvement briefly,all this occurs in all gears ,if I press the accelerator more the whole engine starts to shake . Being a certified novice A is there a connection between what's been done and what's happening now or B should I be looking for something else , all comments thankfully received ! :)

Have you popped the bonnet to check if a boost hose has come off or split?

Could be the orange seal split/not sitting right?

Thanks for the reply yes I've had look and tried to see if anything is obvious on the boost hose I'm supposing you mean the grey pipe with the rubber on the end and it was very firm on the injection end but not so firm on the orange end near the turbo but there doesn't appear to be any splits on either end .

Checked the seal the Orange one and it doesn't seem to be sitting right underneath and there are some small splits on the edge so I've just ordered a new one ,fingers crossed it's the culprit.

Where did you get your New Exhaust Manifold from?


Some mistakes are too much fun to only make once.
There are times when I think the gene pool could do with some chlorine.

Getting the pipe and new orange gasket fitted is proving tricky is there any trick to getting it lined up at both ends or is it just trial and error :D

You get used to it! Put some silicone grease (or washing up liquid) on the inside of the orange seal - that makes it slip over turbo air output more easily and try to fit both ends on at same time.

OK, In your first post it was "having recently had a new exhaust manifold fitted" Now I realise it was just the gasket, thanks.

The good news is I've fitted back the pipe with the new orange gasket and it's definitely the cause of the power loss ,the bad news is I can't clip it on to stay for very long it blows off very quickly ,I believe the original pipe had a clip spot welded on the turbo end this seems to be missing from mine although its original,I've used a motorcycle silencer clip which was on it ,but it seems to slip ,any further excellent advise will be welcomed :D

I think it might be time for a picture as you mentioned an intercooler? The original crossover pipe is reasonably well located as it just goes from the turbo straight to the throttle body so doesn't get the opportunity to move much anyway..

Hi Phil , don't think I mentioned an intercooler ,the pipe blows off as soon as the turbo kicks in :D
