davidwort 0 Posted November 28, 2003 Looks like my 16v cylinder head might be due for a rebuild :( It had a rebuild about 5 yrs and 30,000 miles ago, mainly for porting and polishing, but I don't think the valve guides were replaced. I seem to be using about half a litre of oil every couple of hundred miles. Wierd thing is, no oil in the coolant, no leaks from cam cover, head gasket etc.. and very little blue smoke, I'm guessing it's stem seals and possibly guides, but I'd have expected plumes of smoke for this much oil use. So where is it all going? cheers, David. Quote Share this post Link to post Share on other sites
h100vw 0 Posted November 28, 2003 How many miles on the rest of the engine? Could be normal engine wear if it's done over 100K and been mistreated before you bought it. Duff seals and worn guides will definately increase consumption. Most likely seen on start up and on the overrun. I would be surprised if the guides and seals were not replaced when you had the head done. But, if only the seals were replaced, then the guides have got another 30K on them. New seals on old guides, will only reduce oil consumption short term. Cheers Gavin Quote Share this post Link to post Share on other sites
davidwort 0 Posted November 28, 2003 bottom end is a new TSR 2.0L conversion, about 15,000 miles on it now, hope it's not a broken oil scraper ring or something, seems more lik ethe head, but I'm darned if I ever see any smoke from it, have to get someone to follow me down the road I guess.

stevemac 0 Posted November 28, 2003 VW oil usage recommendation is 1 litre per 1000km (600 miles) before they would take the view that you have a problem. Most 16v engines are designed to use a certain amount of oil & topping up between services is common. I would speak to TSR and see if this may also be a charachteristic of their 2L conversions. I have to say, I'm surprised that the valve guides weren't replaced when the head was done. Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted November 28, 2003 Maybe the bottom end is knackered and oil is being drawn out of the breather and into the lower airbox. I've seen quite a few Golf 16Vs with engine oil streaming down the inner wing because of worn bottom ends. I sincerely hope your TSR lump isn't in that state but it's worth checking. Also check the breather hose isn't crimping under hard acceleration, as this has the same effect as putting your finger over the end of a garden hose. All this is assuming you're still using the factory breather setup, that is! If none of the above, has to be guides. Kev Quote Share this post Link to post Share on other sites
davidwort 0 Posted November 28, 2003 Breather doesn't seem to be dumping much oil into the inlet, only non standard items on my induction system are removal of snorkel and a Jetex panel filter. But I guess the breather hoses are getting pretty old. The strength of the engine on the road leads me to think it can only be stem seals/valve guides. apparently a cap full of brake fluid in the engine oil will soften the seals a bit and might point me to them if it lowers consumption a bit :?: :?: :?: I have a VDO oil pressure gauge too and that is behaving exactly as ever before on cold start, warm up and full temp running. water temp and oil temp behave fine as well. It'll be the fourth time I've taken the head off, so I'm getting quite efficient at doing it now! Give me something to do at the weekends next year anyway :) cheers, David.

h100vw 0 Posted November 28, 2003 What oil are you using???? Have tyou had mineral oil in and then changed to synthetic?? What weight is it? Old dub engines use oil if its too thin. My mk1 2 litre used a litre every 1000 miles on synthetic and next to nothing on mineral. Gavin Quote Share this post Link to post Share on other sites
davidwort 0 Posted December 1, 2003 It's been run on solely quantum semi-synthetic since the new bottom end, I did run magnatec a few years back but that was on the old 1.8 block. It's rapidly deteriorated in the last couple of months from a pretty constant 1/4 litre per thousand miles to last weeks 3/4 of a litre in 200 miles, doesn't blow smoke when blipping the throttle, it seems to be when you hold the revs (with car parked up), but it's not clouds.

h100vw 0 Posted December 1, 2003 I can't see brake fliud improving matters? Never heard that, sounds like a bit of pub talk to me. Cheapest option has to be the guides. Pulling the engine to re ring it would be a nause. Rethink, cheapest option. Drop the oil out and put some quality mineral oil in it. Quantum blue? Monitor the consumption and go from there. If it's still high get the guides done. Gavin Quote Share this post Link to post Share on other sites
