START YOU BASTARD!!!

Yeah, just pull the belt and the VVT sprockets. I fixed Martin's with a bit of 4mm allen key. Drilled the old pin out and tapped the allen key in after rounding it up a bit with a grinder.

 

Jesus Mike ur not really getting a brake are ya?
hopefully this will be the last of ur probs and you can get down to enjoying the fruits of ur labour :zlove:

will ur setup see the dyno when run in ?

Trev

 

Buy one.

 

It does fit the symptoms mike, the big clues i think are low vac at idle and the fuelly residue in the plenum.

After the last one i was going to make up a modified balance tube that kept each bank seperate so that we could test the vac on either side.

I never got round to it but i suppose it could also be done by just removing the balance tube and blocking off the plenum teporarily.

a difference in vac on each bank will confirm the diagnosis.

The only ohter thing i can think of is the VTC stuck on on one bank, can u check that on the datascan? and possible flick each one in and out to make sure its not the actual vtc unit stuck internally??

 

with some software it is possible to engage the vtc units and apparantly almost stall the car out when engaged.

It is possible that a VTC unit would stick in the engaged position.

Other weird cause could be a severley blocked exhaust on that one bank.


Have u got an old balance tube u can cut and block off like i said.

I think the vacum reading needs more investigation

 

Does the right hand bank pop out of the exhaust when idling?, if you have a balance pipe in the exhaust both will sound the same.

Have you ruled out the possiblity that bank is loosing compression from valves not sealing properly, this will give a fuel residue in the intake manifold and also low manifold vacuum.

Maybe it is time for a leak down test before you pull too much more apart.

 

Agreed

Leak-down test will eliminate or prove that possibility. Have you found the vacuum leak Mike?

 

A leak down test is done with the engine off, remove each plug and fill that cylinder with air while the valves are closed. Leak down test will determine the percentage of air lost over a short time. you can also listen for where the air is going, ie, sump-intake-exhaust, while doing the test. Will give you a good indication of ring and valve seating ability. Leak down test will tell alot more thann a comp test.

 

Got about 3 to chose from here mike, bit of a drive tho mate.

Yeah a special tool is required, try trade tools or repco, it attatches to a compressor, not overly expensive from memory.

 

Have you checked

that the CAS locating pin has not been broken in the cam or on the CAS.
Causing it to only fire on one bank only.

 

Re:- Electrical

As per Karl. Re check the plugs Remove the rubber boots from the back for the CAS, PTS, TPS, and air flow meter MAF. use a small screwdriver and push in each and every electrical connector from the back. The injectors are easy just lissen to them with a screwdriver to tell if they work.

 

I have now got Mikes car at home, have pulled the plenum tonight. Checked and measured the valvetrain, leak down test, bore-scoped the valves, cylinders and turbos, all is good with the expensive bits.

Intercooler needs to be removed and flushed as well as all boost pipes. There is just alot of small issues which added up to a 3 cylinder vg. Should be running by Sunday afternoon.
