We still have lifters even though it is overhead cam? Man, you can tell I've spent to much time around push rods lately.the_head said:Not really (if it is fuel). I don't see why that would cause a ticking noise. Just a question: you did know that the valves are shim adjusted so these engines are like "mechanical" lifters and not self-adjusting hydraulics. These types of valvetrain generally make more noise than the average engine you might be used to.
Oh man I love it when smart people talk. I learn a lot from you guys so when you can describe stuff this well it really helps me out. I know computers but nothing about engines so bring on the info guys.rdfeatherstone said:The overhead cam engine in the Titan is of the direct valve actuation type. No lifters, no rocker arms and no pushrods.
There is a cap that fits over the valve spring and sits on top of the valve stem. The cap has a protrusion on the underside that directly contacts the valve stem. The cam lobe directly contacts the top of the cap to actuate the valve. To change valve clearance as requred, it is necessary to replace the cap which is available in 0.2mm increments. This system is very similar to that found on many motorcycle engines. Except they use a separate shim under the cap that can be replaced. Often called "Shim under bucket" type.
For a MECHANICAL type system. this holds up well and is integral to the longer service intervals of modern engines.
The post above this one explains what it is. I said "like" mechanical lifters. It's just like what most modern sportbikes have these days.TitanHauler said:
I finally located it on TT. I hear taking off the bolt on the engine block is a chore, buy overall worth a try. Thanks Gregg!GreggS said:DallasTitan I think the fix for the tick your talking about is on TT,I'm thinking about trying it,run a new ground wire from beside the battery to the ground for the engine block,takes about a 36 in. at least thats what the tread says.It's worth a shot. The name of the tread is Fix for the tick on passanger side area.This tread has pictures and all!!! Hope this helps!!
