I am a little worried my engine is on its way out. Basicly I drove through Europe last year did 6,000 miles with no problems, rested the van up over the snowy months. Been driving it daily again and it just feels quite tight and tired (only way I can explain it) It doesn't seem to have any guts anymore. (the engine was fitting by the previous owner who said he brought it of ebay)

I have serviced it a few weeks ago, valve clearances, points, plugs and oil. New clutch (There was quite a bit of oil in the rocker covers)

There is quite alot of oil leaking it seems to be getting on the tinware and dripping down onto the belt which is then flicking the oil all over the engine and engine bay. It leaks now more than it every has, as soon as I stop somewhere jump out and there is already probably 4 - 5 drops of oils. Also when I drove the other day for around half hour when I stopped it was smoking a little at the rear, i think oil had dripped on the exhaust / heat exchangers and was burning off.

The pressure seems alright, but the van does seem to be getting hot. When I drove to the volksworld show after around 30 minutes of driving the van was at 220 F a little longer and it was up to around 230 f. Now that would seem fine but when i was driving in Italy in 30+ heat outside it would get up that hot after an hour of so. Later on in the trip when the weather cooled down after an hours driving the van would only be at around 190 - 200 F.

Please help as im not too sure what to do, I've read on vw-resource it could be a 'Blow by problem' or oil pressure switch?

I am tempted to have the engine out after Stanford hall and do a full strip down to see whats going on? any ideas?

Cheers
 
Sounds like blowby, pressuring the engine and forcing oil out of your bottom pulley, which makes the pulley flick it all over the place.

If you want to put a plaster on it you could fit a breather box which would probably stop the oil leak, but you'd still have blowby which will affect the performance of your motor. It sounds like its needs a strip down and at least new rings, possibly new b&p too.

Do a compression test and see what that tells you before you go any further.
 
I had similar issues on my '67 bug. Turned out to be a hairline crack in the case just below the oil-cooler mount which only opened up and seeped oil when warm. Worth doing all the other checks too though (check all seals etc.)

Good luck
 
Running short journies in the cold spell we have had completely blocked the breather pipe with mayonase, replacing with a bigger clean pipe has improved my oil 'signature' on the drive to about a 1/4 of what it had become. ( not the bay but is 1600 AS engine)
 
Well today I did the compression test. All 4 were 50psi max! I tried again after putting a bit of oil in them. Went up maybe an extra 5psi? So any idea's?

As I said, worn piston rings and possibly barrels and pistons too. That'd pressurise the case and force oil out wherever it could go.
 
So last night when driving it was running really rough, on maybe 3 cylinders. Then it would kind of clear after a little while. Then dorve it home last night and it didnt clear and I heard this loud metal on metal banging noise. Really down on power also, managed to get it home. This morning went to move it of the drive, started up fine was running really lumpy probably on 3 cylinders again. Then just died and wouldnt start again?

Im wondering if there is something wrong with the old plugs / leads I put back on yesterday. So will replace them tonight. Or maybe when i put a tiny bit of oil in the cylinders thats buggered it? but thort that would burn straight off? as its meant to when you do a wet compression test!

Its not looking good as have tickets to big bang and stanford hall!!

Cheers
 
Changed plugs and leads tonight and it seems better. So it mite be alright in the short term whilst i can save some money then get it sort good.
