    z20let using oil

    about a month ago i had a major oil leak on my zlet and it needed all of the oil seals and gaskets replacing.

    i had that all replaced and it was fine until today when the trip computer said check oil level again and the dipstick is bone dry

    so i have had all seals replaced (my MPG) and there is no smoke from the exhaust... i think anyway, what could it be?

    Is the oil being used? Or is it actually leaking from somewhere?

    If you have no evidence of a leak or smoke then ttake the bottom hose off the intercooler and see if there's any oil in there (and I mean a lot rather than a bit of oil on the insides of the pipes/cooler).

    If you have a fair bit in there then the crankcases may be being pressurised. My mates coupe turbo did this and it was found that 3 of his pistons were cracked.
