iv got are vr 355 stroker manual and it has are rear main leak when you rev it the engine has are proracer stroker kit from prostroke and 10.5.1 comp ultra light flywheel iv installed are catchcan and still leaks. motor only done 500kms next is are vac pump has anyone installed are vac pump to are efi 5L
correct me if Im wrong, but wouldnt the oil pressure be the same whether it is a stroker or not.. providing your running the standard oil pump?? maybe the seal wasnt inserted flushly and maybe the ring of the seal was not lubricated before installation?? is the seal the right size for the stroker crank??
If your handy with a spanner Id be dropping the box and replacing the seal
