V8 engine rebuilds - common?

[phumy]

Sorry to hear of your dilema, are you sure it was coolant or was it water? If water it could just be moisture and needs a good hot run to get rid of it, after all 200ppm is a very small amount. If it was mine, i would change the oil and do the test again after some time just to be sure that it is a porousity issue or not..

Hi ,
I ´m facing a porosity problem on my Esprit V8 prod 1998 i just purchased. Found 200ppm of coolant in engine oil (oil is given for 3 years old and 3300km).
No visible coolant traces in oil but 200ppm were détected alter analyse. This looks high. I made this analyse because the 2 turbochargers failed (oil leak due to bearing failure on each turbo)
According to lotus cars, it may comes from an engine block porosity problem that i could fix with bars leak additive.
Does any One has experienced this kind of problem on esprit v8?
Merci beaucoup

I am by no means an expert here but I don't think it is a porosity problem, more a cylinder liner sealant failure. The original sealant, I believe didn't have the higher temperature capability of the new stuff and failed, leading to coolant leaking into the oil.

If your engine hasn't been rebuilt with the new stuff then it's likely a sealant issue.

I seem to remember that the coolant channels in the engine are quite tight and any blockage of the radiator with leaves or debris can increase engine temperatures exacerbating the problem, especially in warm climates.
