Hey Yall,
I just installed my Cylinder Head temp sensor under the plug on #3, didnt cut the wires and installed everything as per VDO specs. I also hooked up my oil temp gauge and to my delight, the sensor actually works. Now, the bad news... My engine runs hot....REAL hot. According to Jake, this thing should be severely damaged by now. At idle it'll get up to 350 on head temps pretty quick and stay there. After driving a little it'll get to 400 and stay there, going down to 350 when sitting at a light. If i start cruising at 45mph or so, it'll get to 400 and a little beyond, i think i've seen as high as 450 on there. Just cruising in 4th gear going 45 will do this. The thing is, the engine sounds fine. I was expecting to hear wierd noises or see smoke, but it just keeps thrumming along. What's going on here? About the engine: hydraulic lifters. no lower air diverter (plastic flap thingy) on passenger side no lower engine tin on driver's side pretty much shot seals around the engine tin no warm air guides stock 76 exhaust manifold to cobbled shitty motorcycle dual exhaust, 1 per cyl bank weber progressive carb what looks like a 009 on there (mallory and promaster are on the way) What can I do to lower these temps? is my engine toast? (it seems to drive just fine, if a little slow) It had run-on and was pinging on the last tank of gas (regular) but now i'm running premium and those things seem to have stopped Help me guys, jake, what can i do? timing? too lean? what? |

The steps you should take have already been said. Make a list of those and sort them with the easiest/cheapest first.
Adjust the timing. That's a high suspect and it's cheap and easy. You can find tutorials by searching. Check the classics section. If it turns out the timing was way advanced, you may find that it takes the edge off the heat problem enough to at least give you a little bit of relief and satisfaction that you are making improvements. Find a good deal on a used exhaust system. Anything would be better than what you have. Get all the tin in place that you can. Joe already gave you a lead on sourcing that. Start with what's easy... Whatever you can install without dropping the engine, get that done. Seal the gaps... Replacing the engine bay rubber seals correctly might require dropping the motor (double check that). But if you're creative you can block holes with aluminum tape and block gaps with rubber belting or something flexible that can stand heat. (The latter sounds like a bit of a hack, but the point is, do what you can!) Going that far won't cost you too much and should drop the temps down into a range that won't be causing damage to your engine. Then tackle the harder / more expensive things as you can. My point is, take heart and do what you can. (IMG:style_emoticons/default/smile.gif) Don't let the elephant scare you... Take a bite at a time and get to it! (IMG:style_emoticons/default/beer.gif) |
