ticking

[beentryin]

i just put my 94 gt motor in my ranger runs great.got good oil pressure,andno knocks but starts ticking when it gets hot,ive tightened the rockers down to spec,and i have rebuilt fully ported head,with dual springs.do you all think the pushrods might not be strong enough.and bending under load?

If the pushrods bent that much under load, I doubt they would come back to their normal shape. How high is your compression? What gas are you running... you could be getting minor detonation

not sure about the compression. it dont tick till it get warm but its got over 40 psi oil pressure when warm. im kinda baffled! but it runns strong

It could be your lifters ?

I recently went through the same problem. I went through and pulled my valve covers and checked the rockers and pushrods.. nothing, thought the problem was fixed.. warmed up then the sound came back. Pulled the valve covers again to check if the rockers were all getting oil, fired it up and watched for oil in each rocker.. all was well. when i was finished putting it back together again i started it up and noticed one of my spark plug wires was really close my exhaust manifold, and when i grabbed it and began to move it I felt hot air and heard the noise... My spark plug had broken around the porcelain in the middle so it was blowing by the spark plug making that perfect valve slap noise haha!

If this isn't your problem try checking your rockers for oil. pop the valve covers and start it up.. I have the 3.0l and it didn't make a mess at all, but im not saying by any means you will have the same result haha. Just glance at each one, sometimes it makes it a little easier if you bump up the idle a little bit if it is hard to see the oil.

yeah this a 5 liter there all getting oil to them some faster than others.and runs really smoth except for the choppy idle from the cam. i think im going to replace the push rods. they are out of my old motor.thank you for the info
