It is a gear driven camshaft with pushrods to the overhead valves. The injection pump is also gear driven off the crankshaft. No timing belts, no timing chain..isn't life good?
I don't understand, are you doing a timing belt on a 4cyl or a timing chain on a v6 ether one it's a job you provably want to have done for a profecional mechanic that have the manuals and tools for this job don't even try
There are several configurations of engines; the older overhead valve conventional cam, overhead valve with overhead cam or cams utilizing chain drive, overhead cam engines with staggered chain drive, gear driven overhead cams and the most common belt driven overhead cam engines. Although each engine has its own specifications, developing the skills to remove Autocome cdp pro
