Diesel engine queries

Post by Al Housman »

Three questions popped into what's left of the brain whilst seeking the source of an oil leak on the 1.6 TD Doka.

1.The leak is from the head gasket on the right behind the injectors.Is there any mileage in tightening the head bolts or am I best leaving it till I replace the gasket in warmer weather?

2.The turbo cooler (I think that's what it is) pipe is flopping in a useless way near the air filter box and seems too short to get near the turbo.Should it be lengthened to blow directly onto the turbo?

3.There are two reasonably large bore rubber pipes (similar in size to the top hose) on the right hand side of the engine which go nowhere.They could well be breathers but seem a bit big-but hey what do I know?Any thoughts anyone?

I've looked through my 'so wird's gemacht' manual which is generally good but hasn't anything about the above.

Cheers
Al

Better ask better brains than me... I might give them a quick try at 45 degrees each to see if they liked it or not....

but sure the leak is not the cam cover, its fairly common, they distort.

Big fat pipes might be breathers from the bellhousing to prevent water getting in? Has one a sort of U shape ends up pointing downwards?

The blast air pipe should terminate in some sort of flat nozzle I think, pointing fairly close to the centre bearing assembly of the turbo...

Thanks for that.
The pipes are almost certainly breathers in that case.Typical German thoroughness to make them that size!
The leak is from the head gasket area:oil oozes out after you've wiped it-I'll consult with my friendly local VW mechanic about tightening.
As to the turbo cooler,it seems an easy enough job.The fan does kick in after a long uphill climb(actually a long upmountain climb)but cuts off pretty quickly.I've spent a fair few days uplifting my lads and their mates at the local downhill cycle course-we've managed 8 bikes and boys so far in relative safety and comfort-which also gives me the opportunity to play a bit too!

I must admit to being really impressed with the syncro as a work horse.And it's good to have a warm. comfortable ride home after a long day hedgelaying!
