Hiya guys, after building my ej20 turbo, was running nice for about a week, now it seems to be drinking water, cant see no water leaks , i have got a oil leak towards front of engine , oil over the drive

brought me compession tester, thinking hg has gone?

Will put results up later....

 

Well water seems to be fine again. have noticed the seal on my exspansion nottle cap half missing, would this cause a problem?

Also noticed oil leaking from underneath, checked and coming from bottom of cambelt covers...might sound daft but why is oil coming from there?

Thanks

 

Well had a read and seen crank seal, oil pump seal etc

 

what were the compression test results?

 

it would have to be a very badly blown head gasket to show up on a compression test, in fact so bad it would not be firing on the blown cylinder

 

crank seals tend to go at around 100kmiles. the front one is quite a simple change. the rear one is a pain. If the cap is tired then you will lose water from there when up to temp and reving a bit.

hopefully its the cap... but maybe sniff test to make sure. compression test doesnt always show a leaking gasket unles really gone as stated above. no harm in having a look at pressures though.

 

Oil leaking from inside of the cambelt covers can be:
Oil pump seal
Camshaft seals
No sealant on front cam caps (seal carrier caps)
Lack of sealant on crankcase halfs especially above and below oil pump mating face.

Didnt do compression test today, was pis*ed off with leaking oil, and now the snow is back over my area, ggrrr ,
Yeh i got 130,000miles on mine, just seem problem after each other, if weather gets better tomoro ill be stripping it again, and order a new cap.

Went to couple garages yesturday about sniff test, but didnt do even ats i went to, sure ill find one

Water seems fine, waiting for new exspansion cap to arrive, seems oil from front seal but going to put in garage this week hopfully and todo cambelt etc,
