my cat wont heat up

The not geting hot would not bother me to much might just be a stuck thermostat but the using a gallon of oil a week..... I think you need to have a talk with the mechanic!

 

Ohhh,that kind off cat heat? Sorry...

 

It's a fact that some sets of rings tend to take longer to seat than others.


I forget which takes longest.....hard chrome rings a bell as hardest to get to seat......correct me if I'm wrong.


I had a Cummins N14 that used oil for about 3 PM cycles before it got completely "DRY" oil consumption wise.

 

LMFAO!!!!!

 

He could of cracked an oiler ring putting it in. I seen it done before.

If he changed the Tstat, he might be having a hard time and has it ####ed a little or old gasket material left on. It doesn't neccessarily have to be stuck.

Chrome rings do take a long time to set Big Red. I'm sure it's just an OEM kit rebuild.

 

To test it you need an infrared temp gun they are cheap. with the engine cold, start it up put it to 1200 RPM, and test the tempature at the oil cooler, that gives you engine tempature, top rad pipe, will tell you if the thermostat seals are leaking, there should be no coolant flow until the thermostats open. Also you have to check the bottom rad pipe, that checks if the vent hose is putting threw so much coolant it is stopping the engine from coming to tempature. If you have a top to bottom flow radiator, with the surge tank on top it could be venting to the core threw there also.
Test what temp the thermostats open when the top rad pipe gets hot, and when the fan comes on the fan must be off at least 10 degrees before the thermostats opening temp is.

 

just for giggles, is the fan staying on most of the time?

 

My fresh 3406E used one gallon the first 5000 miles... then three quarts the next 5000 miles and now, at 17000 miles, nothing....
