Hello people, Im a noob, I just bought a 98 Porsche Boxster but have problems : (

[dti]

do you guys recommend removing the heat exchanger yourself? and also do you recommend getting the Bentley manual? I was doing some google searching but couldn't really find any helpful links to the heat exchanger, I just found a bunch of other people that have the same problem : ( sorry for the trouble and for being such a noob! :dance:

[dti]

thanks Little bastard, Im just going to work at it little by little, But I'm in no hurry to fix the car, it'll be a learning experience : )
one more question. Does every shop have a tool to check the heat exchanger. OR is it only German or Porsche shops?

If you're going to work on the car, buy the Bentley Porsche Boxster Service Manual . This link is the cheapest and includes Free S/H.

The book will pay for itself over and over for the DIYer.

And, instead of spending time here asking loads of questions, you can spend the time fixing the car.

The Heat Exchanger is really called the Oil Cooler. There isn't a special tool to check it - it has no moving parts and is either leaking or it isn't. The only real check is to pull it and pressure test it.

Cheers!

thanks little bastard I will be on it!

sorry for the repeated question. Anyone has a link to remove the heat exchanger ? (oil cooler) I just ordered the Bentley manual so I promise no more questions until later : ) hehe

PM sent....

so reading from sites it has to come out about 150 for each cylinder? my mechanic will do a compression test tomorrow

[dti]

so I did the compression test and the results state that there is no head damage:

1 st head on the drivers side:

170 ( 1st puff got up to 80)
160 ( 1st puff 70)
160 ( first puff 65)

2nd head on the passenger side

165 (1st puff 80)
150 ( 1st puff 80)
160 (1st puff 80)


So I guess this means the culprit has to be the heat exchanger?
can't be the thermostats or waterpump since that doesn't cause oil to go into the reservoir cooling system right?

I am going to take out the heat exchanger and have it pressure tested next just to make sure and pinpoint the trouble.

But thank god it's not the heads. When taking out the spark plugs I noticed that they were really black so it's running rich. The mechanic said if it was the heads or gasket at least one of the spark plug would be clean because of the coolant. :dance:
