Ok New engine after it blowing up

 

Check all timing and all aligns up

0 on crank and all cam Markers on the back plate align

 

New injectors

New Injector plugs

New Plugs

tryed 2 lots of coil packs

even my old injectors

 

when i can get the engine running its sounds nice ( engine )

no knock/bangs/taps

Oil Pressure is right about middle on ide>2k

 

the engine will not go past 3k as it dies out

 

the miss fire is mainly on the passenger side bank

 

does any one know where the wires normaly brake or

know of a good Loom thay no longer need

 

Please help

Maf or put conections

check your ptu connections

Have you had the ECU plug off?

BTW,don't put too much creedance on the cam belt markings-there just for a guide.

well there are other markers with the belt and some tip-x that some ones done and thay all align up too

 

all connections to the PTU/Maf are spotless

yes i have had the ecu out but it was the same before tuching it ..

 

only had it out due to Rechipping it but thats all the same still with new injectors

 

its starting to worrie me now that there is a problem with the engine

Just that Boldy had a misfire and we took off the Ecu plug and re-seated it and solved it.Doesn't take much to bugger the connection up.Worth a look?

Well just to throw this out there, the PTU connections might be fine, but the PTU itself might be fubarred! The connections came loose on mine last week while I was in london and the car still ran, but the passenger side was lumpy as hell! and the car sounded like it literally had bolts in the cylinders, it also wouldn't rev above 3000 revs, all of what you're describing sounds exactly like what happened to me.

 

Once I plugged the PTU back in, it ran sweet as a nut! I've been told PTUs tend to just die, no warning whatsoever. Can you swap that with a known good one?

 

BOOT NOTE: I'm also told when swapping a PTU, take your battery off!

oh ... i never disconected the batt ...:crying:

 

any one got a S2 PTU to sell me

its the Black one

hi mate when i changed my engine it had what seemed like a misfire played with everything ended up being one of the lower turbo pipes the big one that goes right to the front thats a bit of a pig to get on lol.

 

Hopeu sort get it sorted.

all my pipes are ok .. checked them all and replace with suspect ones ..

Have you checked that the ECU plug is not too tight? Sometimes these can be over tightened and cause all sorts of problems.

my pipes were ok just wasnt on properly right down at the front.

When they dont rev past 3000rpm normally maf, was thinking if you had air leak bad enough may not pull the air past the maf give you similar problem,

 

nightmare cars lol.

ecu is fine i have checked it twice and the connections are clean .. plus this fault was there with diffrent injectors and new ..

 

but what is making me thing

when my engine went bang oil pump stopped working and made the engine very very Hot ..

i'm not just thinking it could be the ptu

i would also say possibly maf. or a loose connection sum where. might be worth having jeff have a quick look at it he isnt too far from you.

yeah gonna speak to him

I'd say it sounds a lot like PTU to me tbh, surely someone lives near you with a PTU you could test just to make sure? Mines an S1, or I'd drive down to Derby for ya, lol.

 

Does it seem like the middle cylinder on the passenger side is just not firing? If you stand behind the car while it's idling, is the drivers side exhaust smooth and the passenger side, rough but in a predictable and routine manor? If so, sounds EXACTLY like when my PTU became disconnected. Another thing for me, was if I did try to force it over 3000 revs, it backfired a LOT!

i get a pop from drivers but mainly on passenger side ..

 

yep pop pop bang bang smell of fuel

I would defo being looking at the MAF or connections, or at least the mixture, as I've had similar problems with other cars in the past. It sounds like the engine is getting too much, or too little air. This is all based on non turbo knowledge. never had a turbo :( , but could help... Maybe look at the TPS too, but don't think that's the prob, but you never know....

little update ..

got a brand new PTU from Zedcentre .. Cheers luke for the Deal

and it seems to be better but still missfiring ..

 

got some new coil pack plugs/leads and new ptu leads gonna see what happends chaging them over later on .

Good luck mate, shame the PTU didn't fix it, but at least you have a spare now in case it does go wrong.

yeah cheers ..

 

its not going to beat me ...

seems to be that everything has changed but the maf. i really think you should change that, or at least do a quick test on it.

That has been changed too i have 3 here....

Have you tried a boost leak check.

Also have you checked all the plugs on the right hand side around balance bar.

Air regulator and injector plug are really simillar.

and think the knock sensor and 02 are too.

all brand new pipes on the boost side and 80% of the vac pipes have been replaced ..

do need to do a vac test

 

i have had 3 lots of sparkys

2 lots of coil packs

 

i now have brand new Coil pack connectors

Brand New PTU and Connectors

Brand New Injectors and Connectors

 

i have the right connections as all was Numbered up

 

the Nock and O2 sensors are diffrent plugs 2>3pin
