timing gear

Hello everyone.

I have changed the timing gear . and now i have cooling problems. the timing is spot on. i have flushed the radiator and engine. controlled top dead center. the positive stop way. it was also all right. cooking the thermostat. water seams to to be circulating. i have testet for blown head gasket. with block tester fluid/Kit. it idles long time with no overheating.
but at highway speed 55-60 miles. it builds temperatur. if i have timed the cam a tooth wrong can it cause to overheating? . is there a way to check the cam timing without taking the timingcover off. i was thinking about taking the valve cover off and using a dial gauge indicator. i have the valve timing specs . but is there anybody here that can tell me how to check it before i take it all apart again for maybe no reason.
looking forward to hear from you.
best regards multi.
 
If the actual radiator itself has blockages within the cooling fins, then flushing won't make a difference. Air needs to circulate through the radiator, but with a blockage from insects and dirt over time, the ability of the radiator to cool, particularly at speed is compromised. How old is your radiator? When was the core last replaced?

Aside from that, what did you intend to set your timing chain at, how many degrees advance? The standard morse chain with the nylon teeth on the cam wheel would guarantee retarded camshaft timing of varying degrees with no ill effects on engine cooling efficiency.

Are you sure you have got all the air out of the cooling system and are not suffering from air locking ?
 
As cobraboy intimated. The P6V8 is notorious for air locks.
Have the car facing up hill and then recheck your levels.
I put mine on ramps to create a hill. Run it without the cap. Surprising amount of fluid level drop.
 
Thank you very much. i did put the front end on a pair of ramps. when heating the engine up, it was a hit. sure i got it now.
best regards. Multi
 
Dont neglect to check igntion timing - badly retarded timing will also raise the temperature under load. After an R&R of the distributor, which is implicit in a timing cover change, always redo the spark timing.
