skirkland1980 Posted September 18, 2012 Share Posted September 18, 2012 Hello. I just replaced the head gasket set on my L28ET. I also replaced the valve stem seals supplied in the felpro gasket kit part number HS8799PT-1. Now my engine is burning a lot of oil. I'm thinking the valve stem seals are the problem. Has anyone had any experience with these felpro seals? If so which ones should I use? I found these. They are said to be OE. http://www.autopartswarehouse.com/sku/Nissan/280ZX/Ishino/Valve_Stem_Seal/1983/Turbo/6_Cyl_2-dot-8L/W0133-1644072.html?tlc=Engine+%26+Drivetrain Thanks Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted September 18, 2012 Share Posted September 18, 2012 I've seen guys put on the valve stem seals and put the valves through it only to remember that they forgot something and had the pull the valves back out through the seals.....which usually takes a small chunk out of the seal. They will leak after that. I did it the other day on a head I had stored just after rebuilding it and I had to re-lap the valves. When I pulled the valves through the seals, I noticed very tiny and thin "C" shaped parts of the seals in the groove for the keepers.

skirkland1980 Posted September 18, 2012 Author Share Posted September 18, 2012 I started out using the sleeves to protect the seals when installing them but they seemed fine so I stopped using it. Maybe I damaged them and didn't realize it. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted September 19, 2012 Share Posted September 19, 2012 Before taking the head apart, I would check if it is sipping oil from anywhere else that is easier to fix. I've seen cars drink fluid through the automatic transmission modulator (if you car has that) and also seen pcv systems that are inoperative cause enough crankcase pressure to prevent oil from leaving the turbo and instead seeping into the turbo.

skirkland1980 Posted September 19, 2012 Author Share Posted September 19, 2012 Well I pulled the intake and exhaust manifold and it is the stem seals. So I pulled the head and removed the worst one and I see nothing wrong with the seal. I guess I'll try to find some seals from Nissan.

skirkland1980 Posted September 19, 2012 Author Share Posted September 19, 2012 I just got a quote of $56 for Nissan seals. Does anyone know of a cheaper route that would be of the same quality? Quote Link to comment Share on other sites More sharing options...
NewZed Posted September 19, 2012 Share Posted September 19, 2012 Search "ford valve seals" something will come up. Don't know if they're cheaper. Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted September 19, 2012 Author Share Posted September 19, 2012 So Ford uses a similar seal? Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted September 20, 2012 Author Share Posted September 20, 2012 Hey thanks for the ford info. I did a search under a 1990 ford bronco II 2.9L and the seals came up to $4.99 each. Then found the sticky. Turns out to be a common problem after all. Guess this one's on it's way to the tool shed. Quote Link to comment Share on other sites More sharing options...
NewZed Posted September 21, 2012 Share Posted September 21, 2012 Don't forget RockAuto. They show some low prices there. Quote Link to comment Share on other sites More sharing options...
