Ferd/289 Posted December 22, 2004 Share Posted December 22, 2004 Here is a question that i have been thinking about. Can too high oil pressure ( i.e.90lbs) raise the pressure in the crankcase so that the dipstick pops out. I know that PVC or breather valves on the valve covers relieve high crankcase pressures caused by blowby. But can the oil pressure routing cause undue high pressure in the crankcase in and of itself. Ensuing damage could be seals leaking etc. Ferd. Quote Link to comment Share on other sites More sharing options...

Ferd/289 Posted December 22, 2004 Author Share Posted December 22, 2004 tried to read your url but goes to Hybridz search. When I search I find nada. Ferd Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 22, 2004 Share Posted December 22, 2004 Oh, sorry. The sig link is kind of a joke, so that people look at it and it is the search screen. Since my answer was so short it kinda looks like I'm telling you to look at the link, but really it is just my signature. Dry sump motors don't blow the dipstick out though, so the answer to your original question is no. Quote Link to comment Share on other sites More sharing options...
GabeRoc Posted December 22, 2004 Share Posted December 22, 2004 even in a wet sump motor high oil pressure won't cause increased internal engine pressure. if you have high crankcase pressure odds are it's the PCV valve. --gabe Quote Link to comment Share on other sites More sharing options...
80LS1T Posted December 23, 2004 Share Posted December 23, 2004 Yeah when the PCV stops working it often causes oil leaks from places like the valve covers, oil pan gasket, and front crank seal. Atleast thats what Ive seen. Guy Quote Link to comment Share on other sites More sharing options...
