Question about 2005 Suzuki RM-Z 450

1 Answer

My 2008 Suzuki RMZ450 is leaking oil from the head gasket pretty badly. I have changed the gasket 3 times now with the oem gasket and it still leaks. It looks like a few other gaskets such as from the cases to the cylinder also leak. Could this have something to do with the oil not being able to get back down the the bottom end efficiently? What can I do to fix it? The motor was pulled apart around 15 hours ago and got all new gaskets and top end then. Running synthetic 10w- 40 and a rekluse z start pro clutch.

2008 Yamaha TTR230 cylinder head leaking oil

Re torque bolts on left bottom side of head to 17ftlbs if you can not get a torque wrench in there use a #5 allen and go a quarter turn past snug. This should stop the leak and reseal the gasket. If not you have to change the gaskets top and bottom.

White smoke out exaust pipe and stalling

Any time there is white smoke coming out of your car's exhaust system, it is an indication of a leak. but a leak that is allowing either oil, coolant, or transmission fluid to get into the cylinders. The smoke is from the leaking substance not getting completely burned off like the air and fuel mixture does under normal operating conditions. pull the oil dipstick and see if you have traces of coolant in oil. if so you have either a bad manifold gasket or a head gasket went bad. good-day !

It has thick white liquid along with oil on end of dip stick every time i check oil.I put a liquid block sealer in motor, I went step by step of directions.Even changed oil and oil filter 3 times in a 2...

The head gasket is bad and needs to be changed. Block sealer won't work on bad gaskets that are beyond it's ability. The trans is probably leaking at the front seal for the second problem. You would have milky fluid leaking there if it were the rear main.

Where is the oil level indicator on an rmz450 2008

The isn't an oil level sight glass as such on the '08 RMZ450. About halfway up the clutch cover is a allen key head bolt. Run the bike until it's warm and then turn it off. Wait a couple of minutes and then take out the screw. If the oil level is correct there should be a slight dribble of oil coming out of the bolt hole.
