Makesure you get this type valve stem seal not the cheap shit ones the motor factors have

Moonie

Easy enough to change the stem seals. Just make sure the piston for the cylinder you are working on is at TDC incase the valve slips through the guide. Also be careful with the valve collets, a bit of grease on the valve stem will help hold them inplace.

Use the above stem seals and this tool....

oil in the bost pipes is pretty normal if it's just small amounts as the breather will vent a small amount back into the metering unit which in turn goes into the chambers.

There just standard CVH stem seals for all the CVH models

Moose

i fitted that type of stem seal, i fort a small amount was normal, but i took the cross over pipe off and it had a bout 7/8mm thick line at the bottom and in the pipe where it connects and its coming out of my dump valve too onto the air box, soo i took the pipes off and washed them out, the week after i checked again and it was back to the same state

ps i only have a dump valve fitted cos i dont get chatter and sick of ppl thinkin its a replica

Moonie

Worn stem seals will not cause oil in the intake system/boost pipes.

Are you still on a standard breather or aftermarket breather that is still connected to the metering unit (ie - not vented to a catch tank/atmosphere)?

Moose

i knew that they wouldn't cause oil in the intake but i dint know bout the oil in there till i changed the seals , still on standard breather i fitted a new brether filter and i made bit less smokey so would a bailey breather maybe sort it? any ideas?

i had this problemw ith mine and later found out the turbo oil seals had gone.... might want to check for oil in the turbo entry pipe that goes from the bottom of the metering unit (air filter/fuel unit) to the main intake of the turbo. If that pipe has a recent trace of oil i would put my money on turbo seals. Oh and it doesnt have to be plooming out smoke for the seals to be gone. oh and thought i might add.... i changed my oil breathers too and still didnt sort it.

Moose

i was startin to think that was the problem, cheers mate, need ro get a turbo now , anyone got a spare one?
