Re: Hot engine
Mine would continuously run at around 220 - 230 on long trips , and while it wouldn't lock up or boil it did "ping" at the slightest increase in throttle .

Re: Hot engine
Ron, are the ross pistons forged,and are they quite at .004.
I have a set that I thought I would use in a road engine but was worried about them being noisy until the get warmed up. Lawrie |

Re: Hot engine
As A teenager MANY MANY years ago I blew a lower radiator hose on a 48 Merc. Convertible coming over the Cape Cod canal and shut it off in Hampton N.H. ! I remember down shifting a few times when it started to slow down. Stopped once and added a lot of # 50 oil from a 2 Gallon can but never shut it down. It crackled for quite a while as I remember it. Started it up next day and drove it home no power but it got me home. TODAY I would not drive it if gage hit the top.

Re: Hot engine
This thread brings up a related topic..... there are coolants available now (Evans is one) that will go to around 395 F before boiling. The people advertising these coolants try to give the impression that if it doesn't boil, it's not doing any harm. That makes no sense to me, I can see the overheated block developing cracks around the exhaust valves, and surely the oil must get very hot and thin out.

Re: Hot engine
my 49 overheated constantly even after changing pumps, oil, rad flush, head gaskets. i was pretty flustered cause no mater what i did it would climb up to the "H". then one day i said what the hell and hooked up a timing light and found it was waaaay off. a quick adjustment of the dizzy and now it dosnt go past the halfway point on the guage. oh i put 160 stats in too.

When you ask if you should shut her down at a certain temp. That can be just as bad. When you stop moving forward(air flow) or the fan stops moving the air. she will get hotter for a while. You are better to ease the load, and let the temp come back. If she is getting hot because you are hauling a load up hill, you are better to slow down, drop a gear, and ease up on the throttle (fan moving more air) than to stay in top gear with the throttle down. It's a matter of driving her like your running her in, balancing the throttle against the temp gauge. Is any of that helpful? |
