samurai help

[ericevans14]

i have a 1986 suzuki samurai that has a rattle in the top end and seems to be valves because of lack of power, i was wondering if any body knew how to adjust the valves before i pull the valve cover

[sturgeon95]

With a cold engine set the intake 0.13-0.17mm and set the exhaust 0.16-0.20mm Make sure each cylinder is on top dead center when adjustments are made, Check and then double check. If they are too tight you could burn the valves.

If the rattle is that bad, check for a broken valve spring too. Valve adjustments are very easy on the Samis, takes no time, if the valve cover hasn't been off in a while, get a new gasket set.

Kinda sounds like a rod bearing, could be a main though, either way, not a good thing.

yea i think its a rod bearing so ill go to the old pull a part and pull a motor

You can get the pan off without pulling the motor if you want to evaluate before yanking it out.
