Adam W Posted September 24, 2003 Share Posted September 24, 2003 You need to be burning a SHITLOAD of oil before you can see it easily out the back. The head needs to come off to get at the stem seals (I can do that in five hours now on my Mk3!), if your timing belt is getting on a bit you might also take the opportunity to get that changed. Steve - you say those symptoms are classic stem seals; how do you know its not rings? Mine is still consuming oil with a new engine, I'm hoping its the (older) stem seals causing the problem, how can I diagnose it for sure either way?

Guest Terry S Posted September 24, 2003 Share Posted September 24, 2003 Adam, get Leon to do a leak down test. Link to comment Share on other sites More sharing options...
Adam W Posted September 24, 2003 Share Posted September 24, 2003 That would work, but the results might be skewed by the fact that my block is in the car and my head is on my workbench Link to comment Share on other sites More sharing options...

Steve W Posted September 24, 2003 Share Posted September 24, 2003 Ad'... rings is usually more pronounced the longer you rev it not just a short/sharp puff as you accelerate - which is more what Mawlies was doin' Sunday... he got the typical 'WOOF' as he booted it, then.......clear as a........a........ Soop ! Can't you get at the Seals with the head ON ? ? Usually the ONLY reason why you need to take the head off first is when you can't take the cams out in situ ! ! (ala OHC / BMW's etc - correction, OHC you can cut a HOLE in the bulkhead and take it off thru the dash ! ! ! = TRUE ! !) OR, are the seals SO deeply inset that you can't get a tool on them in there ? ? (OOOPS, forgot to ask the lads about times/tensioners etc.... I'll try to remember tomorrow...... honest !) ForgetS. [ps... IF it's rings, bad enough for smoking, it should show on a compression test anyway ? ? - maybe ? ?] Link to comment Share on other sites More sharing options...
Terminator Posted September 24, 2003 Share Posted September 24, 2003 I think there is some stuff on MKIV.com about doing it with the head on. Tricky but possible. Link to comment Share on other sites More sharing options...
Adam W Posted September 25, 2003 Share Posted September 25, 2003 Thanks Steve. I took the head off mine to, errr, fit a new gasket Bloody Mk3's! Phil, you can do the stem seals on the Mk3 and MkIV with the head in place but it looks like such a fiddly bastard of a job that I reckon it would genuinely be easier to take the head off. More chance of doing the job right that way and not damaging a seal as well. Link to comment Share on other sites More sharing options...
mawby Posted September 25, 2003 Author Share Posted September 25, 2003 Well I filled up with oil yesterday, drove like a grandad to and from work for 120+ miles with only a couple of seconds of boost - a vacuum of -.5 bar most of the way. Then this morning I checked my oil and it was down to half way again! I've seen no puffs of smoke or anything, so I guess it is the stem seals or the PVC value. All I need now is ToyodaTech to answer the damn phone when I call them! Out of interest Terry, if ToyodaTech are fully booked for weeks on end (like they normally are) and I can't get my car in within reasonable time, when could you fit it in and how long would you need the car to diagnose and fix the problem assuming it is stem seals? Also, is there anything else I should get done at the same time? It's only recently had a cam belt change so that doesn't need doing. I'd like to get big injectors, uprated fuel pump and rail but probably couldn't afford it all in one go. I just hate it when things go wrong with my car!

Guest Terry S Posted September 25, 2003 Share Posted September 25, 2003 Lee, you'd really need to ask Leon, I don't work with him, just mates. 01908 367100 I would honestly blank off the PCV Valve today and do the same as yesterday. The chances are it's not this, but if it is you've had a result. Link to comment Share on other sites More sharing options...

I'll just have to carry a barrel of oil in the boot of the car! Cheers for all the advice people! Link to comment Share on other sites More sharing options...
Guest Terry S Posted September 25, 2003 Share Posted September 25, 2003 To blank off the PCV takes 5 mins. Just disconnect the rubber hose from the PCV (which is in the cam cover). This will leave you with the rubber hose from the intake. Put a bolt in the end of the rubber hose and secure with a jubilee clip. If you have another piece if hose, connected it to the PCV ( don't be rough with the valve BTW) and run the new hose into an old coke can or coffee jar, like a temporary oil catch tank.

Steve W Posted September 25, 2003 Share Posted September 25, 2003 asked the lads at work today (the 'repair' geezas !).... they both said VERY tricky to do ON ! ! ! SORRY matie...... looks like a Head-Gasket-Jobbie/come/refurb-Head sort of touch (do it all at once).... APPLE-OGGYS for raisin' yer hopes there ! ! (they didn't say impossible, just VERY unlikely/difficult - it's the fact that you 'can't' 'catch' the valve/spring as you try to compress the collet-type-thingies ? ? - ie. most/all BUCKET/shim arrangements would be just as hard) FatS. THEREFORE.... I DO hope it's something REALLY trivial and stupid like a pipe/valve etc ! ! ! (save those squidz fer 'juice') Link to comment Share on other sites More sharing options...
The Restorer Posted December 9, 2004 Share Posted December 9, 2004 Lee, So what was the outcome on this. Also, do you know what oil Totyodatech use? Ta! Link to comment Share on other sites More sharing options...
tDR Posted December 10, 2004 Share Posted December 10, 2004 I know this thread is old and probably was resolved in the manner discussed, but just to add - had a problem with my Supra smoking and losing a lot of oil. Turned out to be the oil pressure switch, the seal on it had perished and was pissing out my oil, it was running down the exhaust area and causing the effect of smoke out the back. It was a £12 part and a couple of hours to fit it in the end.... Cheers, Brian. Link to comment Share on other sites More sharing options...
mawby Posted December 10, 2004 Author Share Posted December 10, 2004 It was the rear main oil seal leaking. Whilst idling this would cause oil to fall on the exhaust which would burn as I pulled away and looked like it was comming out of the exhaust. Everyone who saw it thought it was comming out of the exhaust, thankfully it wasn't so it was just £400 to fix and that included a full service.

tDR Posted December 10, 2004 Share Posted December 10, 2004 That's the same as how my problem looked - everyone that saw the car thought there was something major wrong but in reality it was a very minor thing. Link to comment Share on other sites More sharing options...
