Running too hot up grades at speed

Share this page

Kim, I do think that you have a strange problem!! There should be oil somewhere!! When I was coming back with my wrecked engine, I was burning about the same oil. The bottom of the car was covered in oil!! And smoke?? WOW!!! I had one guy drive by and hold up a sign that said 'FIX YOUR CAR'!! I was pressurizing the crankcase and blowing oil everywhere, and because there was a dent in the cylinder wall, was burning like crazy also!! I would stop for gas and it ould look like 3 Harleys had been parked overnight!!

My point is that I was smoking and dripping and using about the same oil as you!! Anyway, it sure is nice to have it sorted out!! How far from your house to Tom's shop?? A new engine is sure nice!! Next winter you should have your garage!!

Tom,
Please explain. I was talking about internal blowby causing more heat transfer to the water jackets. Normally peak combustion pressure & heat occurs in the first 90 degrees of crank rotation. After that the gasses have lost a lot of their heat in doing the work of pushing the piston down. As the piston moves down more of the cylinder surface area is exposed to the remaining but lesser heat. With ring leakage The maximum heat is exposed to more cylinder surface area as it blows by the piston.

Retarded timing also causes more heat to be transfered to the cooling system because of the same increased cylinder surface area. I expect that you already know the above.

Looking in the open radiator might show a combustion leak into the cooling system which would also create additional heat load -- but I didn't address this problem.

I have delt with a number of cars with enough blow by that smoke was boiling out the crank vent and none of them had an over heating problem. I understand your theory but that's not the problem.If I was her I would have someone check her engine with a remolt temp gage.
 
I understand the theory behind what Dave was saying, but I have never seen a car heat up with blowby either!! Remote temp testing is a good idea!! Have you tried it Kim?? Does the car smell really hot?? You can never miss hot antifreeze!! When I had the dent in the cylinder wall and all the other crap that was going on!!
 
Kim...blowby isn't your problem...antifreeze hasn't been involved...were it either, it would be readily evidsnt....lets go back to what can make a car appear to use oil: have you checked for external leaks? have you checked your PVC/emissions for clogging?
 
And have you checked that your temp gauge is correct!! I think we all agree with Tony, blow by is not the problem! I was running 80 lbs of my new rebuild, changed out the temp and oil pressure gauge and now I am maxing at 70!! Perfect!! The reason I changed it was because the temperature gauge died in Boise!! I was sure that the oil pressure was fine!! Gee!! I hope you find it Kim!!

I would have to agree that you are probably leaking oil rather than burning it. It's amazing how far the oil can travel on the underside of your vehicle before it drips to the ground. Is oil leaking onto the exhaust pipe or manifold? If you have a leak that's dripping onto the exhaust pipe underneath the car, that might explain how you could lose that much oil without seeing a puddle under your car. If this is happening, you should notice the odor of evaporating oil, especially when the car is at a standstill for a while.

As far as the overheating problem goes, you might try removing the thermostat (as someone else mentioned.) Check the hoses to see if they collapse.
 
I've heard complaints about the quality of the water pumps that we are getting.

Apparently the impellers aren't efficient or not pushed onto the shaft enough to actually pump the water.
Has anyone heard of this ??
 
If you are running hot while pulling a grade, retard the timing a few degrees, I bet it helps.
It worked for me. Too far advanced will be nice around town but not on the hills. It should also help with the oil consumption. When my Midget was doing the same, it was leaking oil out of the head and hitting 230*. All due to the timing be just a bit too far advanced.
