Hmmm something bad seems to have happened with the replacement engine I got fitted

 

There didn't appear to be any problem when I picked the car up.

 

The engine sounds OK and it seems to run OK however when I drove it back yesterday my friend who was following me said it was smoking a lot just from the near side exhaust but I didn't notice as the car felt like it was running fine

 

This seems to have gotten worse today when ticking over the nearside ehxaust is 'splutterring' a bit like there is an intermittent misfire on that side and when you rev it you get copious amounts of white smoke from that exhaust - and I mean plenty of it!!

 

I popped to the garage across the road and they had a look and revved it quite a bit and said they thought it was a turbo but could not explain the splutterring so then they said it could be 'just about anything' which wasn't very helpful

 

I parked up outside the house for 15 mins and then asked the missus to rev the car so i could put some video up here and now it seems to be smoking a lot from both exhausts like it just got worse in those 15 mins

 

The guy from next door came out (who also runs a garage) and claimed it is both turbos because if you compress the intercooler pipes with your fingers then rev the engine it should force the pipes back out again against your fingers. You do feel a little pressure 'kick' when holding the intercooler pipes compressed and revving but he says it is not enough

 

I'm not sure this guy knows what he is talking about or not but I must admit when you rev the engine the guage on the boost controller does not go positive it goes from -70 to about 0. I would have to run the car on the road and watch the guage to be certain

 

Any suggestions please, no doubt when I take the car the few miles to Trentham on Sunday (so it can sit there looking pretty even if it is turned off so it don't smoke) I will have 19 more opinions as to what is wrong with my car now :huh: so I may as well ask here first

 

I'll upload the video if I can remember my youtube login lol

its possible but it would have to be a Shit load of oil to bk track that way .. but then again when the car is driving most of the time its on positive intake pressure so it would be blowing out not bk

Mark, what about the EGR picking oil up from exhaust and sending it back to the manifold?????

 

EGR deleted.

haha not that then

EGR deleted.

I did think to myself im sure that and the other obvious stuff like water pipe bypass would have been done esp seeing as the plenum came off.

Honestly, I'm stumped. The amount of oil that has come off those plugs is unreal. I bought a Skyline with a broken RB26DETT, 45psi on cyl 6 from a shattered ringland and it didn't smoke like that or foul the plug that bad. Still made 1.4 bar and pulled (and smoked) like a train. It breathed constantly heavy out of the breathers, smokey just like the exhaust.

 

Here, there's only one bank that's the problem, but I still can't see how a turbo would push that much oil into the opposing cylinders. If it's stem seals, it would smoke blue first thing. It would also likely smoke on the overrun if they're really bad. That white/grey smoke is vapourised oil, collapsed turbo bearings as bad as I've ever seen. If the engine was ingesting that much oil, I doubt it would run, and there would be a huge amount of blue smoke, too. If it was rings, it would smoke all the time. On the video it's only when revved, and there's no blue at all (from what I can see).

Mark, JeffTT, z32bolt......What would happen if the valve on the PCV gets stuck open???

Just reading a few threads recommending replacing them with new ones......... people blaming them for smoke from one bank.....???

Sorry, trying to think of something small and silly that could be another reason......lol

Russ

if the pcv valve was stuck open ... its possible for it to ingest oil from the top of the cam covers ... and would coarse lack of boost only a little... and put positive pressure in the crank casing

in turn this would all so Push oil out of the turbo seals

yes .. just drop them both and check please

get some Pics of the turbo housings where the turbine is

and the amount of oil around

 

when we pop over we can do all the other checks from top

 

 

OK This will be done tomorrow (as long as garage not too busy)

Just thinking dicky96 had plenum powder coated before engine fitted, was the PCV removed and refitted?

I just kept thinking on track days some owners say they have oil dumped on hard cornering and smoke from one side.....

wouldn't leaving oil filler cap loose on tickover stop positive crank pressure just to test if this is the case?

seeing those plugs covered with oil, a compression test will not give very accurate results (as the bores will also be full with oil, giving false positive results)

 

I hope I'm wrong, but it has the symptoms of cracked ringlands.

 

have you tried removing the oil cap while the engine is running ? do you get smoke from the oil cap and/or lots of blowby ?

No bore damage. Failed ringlands letting that much oil in would have smooth vertical sections and it would be impossible for the oil to seal in 180psi with such damage. There would also be monumental amounts of blowby from 3 cylinders (I'm assuming there isn't since it's not been mentioned).

 

It looks a bit like failed ringlands, but all the compression tests & lack of bore damage suggest otherwise.

Hope the blasting media/grit that was used in the preparation of the powder coat process was cleaned out thoroughly....heard of many horror stories of dirty plenums destroying bores.

Hope I am wrong.

Sorry you've asked that several times haven't you yet no ones answered. Firstly the plenum would bee swimming in oil. Secondly the car would burn blue, this is because the oil would be combusted. The thick grey color of this suggests oil being vaporised after combustion. Ie in the exhaust. Also the PVC should be open during idle and all vacuum conditions. It closes when the car boosts to prevent press sustain of the crank case.

Post 121 I. Did answer it

Sorry mark I missed that the page hasn't refreshed when I answered.

no probs m8 ... sorry if it came across a little blunt .. to early in the morning :(

It's alright bud I didn't take it that way.

The downpipes are being dropped today - then I can get some pics as requested

No I havent' actually and don't know if anyone else has either - I can try this later

 

 

If some bright sparks want's to start a FOTM (fault of the month) poll can I enter my car for June please, I think I'm in with a good chance here :clown:

Yeah! Hopefully you will win some car cleaning stuff and you can bob round n clean mine - not parking behind you again!! :biggrin:

PMSL :lol::lol::lol:

Well I am not sure if this is the only problem I have (unless someone can explain how this would cause so much oil to get into the nearside cylinder bank)

 

However I would have to say the nearside turbo is 'not a happy bunny' even though i am not a mechanic

 

Also there seems to be rather a lot of oil under the car in general, on oil feed pipe to turbo, gearbox housing etc

 

He didnt' drop the other side pipe (even though I asked) and says it is all dry around there

 

Also one of the pins is broken off the turbo elbow and there is a nut and bolt in it's place. The elbows are not on my old engine where I got it back - I don't know if this one is off the new engine or old but the garage mechaic said it's 'not very clever'

 

So here is some pics (two sets)

 

Rich

 

Set 1

Second set

 

 

Would the turbo problem also explain all the oil esp in cylinder 6 and on the plugs, and the cylinder drop-out ?.

 

This turbo is the same side that is smoking bad

Just checked one of the other suggestions - there is no smoke coming out of the oil filler cap with it removed and engine ticking over

 

I'm not sure what is meant by 'blowby'

ok you most defo have 2 problems m8

 

Cam cover is Leaking directly on to the tub and in to the plug hole ... Very Common

and the tub its self the seals are shot ..

 

oil around the gearbox is over spray from the oil leak its self
