January 22, 2004i`ve got a `90 305 that runs fine but it has a ticking that comes from the right side of the engine (pass. side). is it a manifold leak, bearing (i hope not). i was told it has hydrulic lifters so it shouldn`t have valve lash. also it doesn`t want to start cold. carnk it over 3 times than stop. crank it over again it starts right up, why? also is there any reason to worry about not having enough back pressure in the exhaust system. thanx in advance.

January 22, 2004could be a manifold leak or a spark plug wire snapping... some of these things you just gotta pop the hood and look for yourself. tehrs so many different things it could be its hard to say without hearing it.
January 22, 2004I have to agree with Nasty on that .... Also hydraulic lifters can go out of adjustment and cause a `valve tap` ... As for the cranking problem, try turning the key to the `on` position and wait a few seconds before cranking the engine to allow the fuel pump to build up pressure ......
January 22, 2004I`ve also seen lifters go bad.. causing an
"out of adjustment problem" and tick...Try changing your oil with heavy weight.. like 20w50 if the tick goes away you probably have a bad lifter.
January 22, 2004Never heard of a manifold leak sound like a tick, so I don`t think that`s it IMO. A bad lifter is a good probability like everyone else said. The 3rd motor I put in my Chevy had a bad lifter and ticked constantly, replaced the lifters and it stopped. As for you hope it`s not a bearing...can`t be. When a bearing goes it makes a VERY loud distinct knocking sound that sounds like the crank is tapping the sides of your oil pan....something like that. Plus bearings aren`t directional since they`re right in the middle of the block, for the crank, or around the center of the block, for rod bearings.
