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? |

I'd worry about the timing and the Weber progressive first.
Timing too far advanced and a lean mixture will make it run really hot. You can probably rent a timing light at a local auto parts store, out here Kragen and Autozone have lots of tools that you can borrow for free- you pay for them, use them, and return them when you're done and you get all of your money back. I've owned a timing light for many years, since before I ever had a 914, but I think that you could set the timing at idle using the "static" timing method. I haven't done it for 20 years, but back when I was into type 1 VW's I would do it all the time. On those, you could connect a timing light to a constant hot wire at one end, to the coil ground at the other end, set cylinder #1 at 3-7 degrees before tdc, (whatever it was supposed to be) move the distributor to retarded, and then slowly move it back to advanced until the light came on. I learned how to do it from the idiot's guide to VW repair. That as probably the best introduction to auto repair ever. I don't have a copy anymore and I'm not 100% sure that that's how it was done or even that it is safe to do with a 914's electrical system, so please don't try it until a couple of other people tell you that it will work and you verify that that is how it's done. Sorry, it's been too long, I'm getting old quickly now. |
