ivantruckman Posted October 19, 2007 Share Posted October 19, 2007 the oil pump gasket broke in one of the ears, it was replaced approx 5k miles ago, the suction deformed it like an egg shape, i was thinking of using permatex silver silicone sealant, and letting it dry overnite ,than bolting it back together, has any one had any better luck, or any sugestions on procedure. thanks ...

GeneralDisorder Posted October 19, 2007 Share Posted October 19, 2007 Replace the pump, they are known to warp in some cases and cause repeated failure of that gasket. GD Quote Link to comment Share on other sites More sharing options...
idosubaru Posted October 19, 2007 Share Posted October 19, 2007 +1 on new oil pump, that's the way to go. i would not any any type of sealant to the oil supply, that's a very bad idea. if price is an issue maybe someone has a known good, low mileage unit available. some over on the XT site have created a metal fitting of sorts to install inside of those ports to keep the gasket from being sucked in. one guy used muffler tape or something, the other guy is a machinist and made his own insert. i don't recommend it and i would never do that instead of just getting a new oil pump. i don't like the idea of introducing moveable, metalic parts that impede oil flow into the oil pump...particularly when it's not necessary.

Reveeen Posted October 19, 2007 Share Posted October 19, 2007 As was stated: it is probably new pump time. You can try hand lapping it on a piece of plate glass (this works sometimes with hydraulic pumps), but a new pump (in this case) is so cheap, and a new motor considerably more expensive than a new pump, that only in some kind of extreme case, is it worth the bother, and risk.

ivantruckman Posted October 19, 2007 Author Share Posted October 19, 2007 i guess ill check it with a straight edge and some feeler guages. hmm Quote Link to comment Share on other sites More sharing options...
Milemaker13 Posted October 20, 2007 Share Posted October 20, 2007 The mod to keep the gasket from sucking in is actually pretty good. You will need a mill or drill press (or a crazy steady hand) and a small piece of copper tubing. Enlarge the suction port just enuff and just deep enuff to accept the "ring" you make from the copper tube. It then acts as a wall to keep the gasket in place... Somewhere here is a write up on it w/ pics. I have not done it, but it sounds rock solid.... Just takes some patience and skill in the machine shop, ya know?

ivantruckman Posted October 20, 2007 Author Share Posted October 20, 2007 cool, should be no problem with the right end mill , i have access to a full machine shop, ill search for then thred, thanks Quote Link to comment Share on other sites More sharing options...
idosubaru Posted October 20, 2007 Share Posted October 20, 2007 cool, should be no problem with the right end mill , i have access to a full machine shop, ill search for then thred, thanks i agree 100% with this being the only way to go. the other thing that i've seen done is to install a piece of metal that isn't rigidly fixed in position, that sounds like a terrible idea. if i were doing this, i'd tap and fit a piece rigidly to the pump.
