Or does it need to be adjusted? I am clueless at this point so help would be greatly appreciated. Re: Oil pressure blowing out filter gaskets?!

As I understand it, the Toyota oil filters have the pressure relief/bypass valve inside the filter: - http://yarchive.net/car/oil_filters.html That could cause problems if running a filter designed for a domestic vehicle which may have the bypass valve external to the filter. r.c.brown@ieee.org TruckEditor@tlca.org Project: 4Crawler 4Crawler OffRoad - 4x4Wire discount code Re: Oil pressure blowing out filter gaskets?!

I tried a purolator and it blew out and two Frams Last edited by poncho; 02/20/06 12:35 AM. Re: Oil pressure blowing out filter gaskets?!

But if the filter is speced for use on Toyota, it should have the internal bypass valve, I think they open around 22psi. Might be some other issues, though. r.c.brown@ieee.org TruckEditor@tlca.org Project: 4Crawler 4Crawler OffRoad - 4x4Wire discount code Re: Oil pressure blowing out filter gaskets?!

Re: Oil pressure blowing out filter gaskets?! [Re: poncho] #698448 02/20/06 02:30 AM Anonymous Unregistered Not on the stock oil relief valve. There's a spring and plunger under that cap. All you can do is check to make sure that the plunger isn't stuck/seized. I did see on a post over at the pirate4x4 forum about an adjustable relief cap that allows you to raise the oil pressure, I don't know if it will let you lower it though.
