Author Topic: 88 TD oil consumption (Read 2643 times)

The engine on my 88 Jetta TD was rebuilt 15,000km ago. The cylinder head is original, has 400,000km on it, and has never been rebuilt. The car currently uses about 1/2 litre of oil every 3000km or so. The engine does not leak oil anywhere (the underside is completely dry, no drips or runs at all). When I start the engine I get a puff of smoke and then no more. During normal use and acceleration it does not smoke at all. Is it normal for these little high compression diesels to use some oil, or (as I suspect) are the valve seals probably bad and that is where the oil is going (into the cylinders and out the tailpipe during startup). Any opinions? It's not too expensive to keep filling it with oil, just kind of annoying after the engine having been rebuilt and all.

Oil is cheap. If you can accept it using some, do so. I just keep feeding them until they use more than a quart per tank full of fuel. That's my personal limit. I know a guy that dumps in a quart every 200 miles and is happy. Whatever works for you I guess.

strangely enough my 1.9td 93 golf with 245,000km doens't drink any oil at all, haven't topped it up even once since the last change, about 6000km so far on motul synthetic 5-40. my vr6 would drink about a liter between changes (about 10,000km)

That's probably what I'll do. The head gasket is six months old and I really don't want to take the head off again. I guess these valve stem seals deteriorate very slowly?
