There are lots of reasons this could happen. When was the last time you changed the plugs and wires, checked your spark plug gaps, checked the timing, even poor carb adjusting can attribute to excessive heat. The dipstick test is hardly science also... you may want to get an oil gauge to help you troubleshoot. |

My distributor was an SVDA it just had the wrong vacuum can (DVDA can) attached to it. The vacuum can went out on me the other day which was the cause of my running problems, I blocked it off and plugged the vacuum ports on the carb and re-timed the distributor to run mechanical advance only. There is a distinct possibility I didn't get it quite right, it is running great but I still get a small backfire every once in a while so I had the feeling it was still off by just a bit. _________________ I'm the humblest guy on this board.

Yes. I was surprised

I had the same issue on a rebuilt engine with 2k miles.
I had all tin/seals/fantastic oil pressure and I checked everything.
After highway driving my oil got too hot and the light came on. (not pressure)
I had the temperature dipstick wired up to warn me when my oil reached 230-240F
Found my problem, my timing at 3500 RPM was at 32 Degrees.
I set my timing down to 30 Degrees at 3500 rpm and it made a world of difference.
My oil temps went down 30-20F !
Also ran much smoother. _________________ (Owner) www.vintagecarleds.com

Well I went for an hour ish drive the other day then outside air temperature was 28 degrees Celsius. The drive included a 40 minute drive in town (a lot of start stop style driving) and a 20 minute drive on the motorway at 70 mph then a 2 minute drive to my house at 40 mph. As soon as I got home I popped the engine lid and stuck the themonitor down the dip stick tube all the way into the oil not touching the sump and I got a reading of 93 degrees Celsius after ten minutes of idle I rechecked and the temperature had fallen down to 88 degrees Celsius. Does this sound ok to you lot? Cheers |
93C = 200F so Yes.
88C = 190F so Yes again.
They are both in the "Normal" range above. _________________ How to Post Photos

hi there sorry if this sounds dum but are these figures for idle temperature or the max temperature the engine should get full stop. |
Max. temp. while driving.
Although I usually check it when stopped for gas since I don't have a gauge.
If you leave the car idling it should never get that hot - it should even cool down if it is too hot. _________________ How to Post Photos

We have seen damage like that in only twelve months on a street car in the past. In the old days when we raced . Once we ran a 3 hour endure in the rain with a new header . After the race we tore down the motor . The header already had rusty water coming from wrap .That stuff is a great horse power and heat retainer unfortunately it also has some down sides ..Another side benefit to ceramic coating, With a squirt bottle it is very easy to see which cylinder is misfiring ,just squirt the tube just past the flange .It will tell you in a heart beat if you got fire in that hole OR MARGINAL PROBLEM lol .JEFF |

I still think the ultimate oil temperature reading would be AFTER the oil cooler, between it and the main bearings, but that's not a very easy place to monitor...
Didn't see this earlier but I want to comment.... Muffler wrap, holy crap, you're not kidding about that rust! I thought I'd try wrap on my Baja bug on the pipes next to my filter-pump oil filter. It did this to my header!:

Well, I have replaced it with the oil pressure relief plug sender now so we will see. _________________ Waiting for santa to drop off funky green. I can wish can't I???? |

There's no oil moving past the sender when its screwed into the oil pressure switch. The temp there is probably closer to room temp than engine temp. It needs to be in the oil drain plug or the oil relief plug. _________________ 1969 Beetle

as far as I know all tin is there. Flaps and thermostat too. I had a tee screwed into the oil pressure switch hole so I could have the light and the temp sender. So the sender was 2 inches away from the hole. If this engines supposed to get 180 even in the winter 21 degree weather then Id better test it or figure out why it ran cold next winter. _________________ Waiting for santa to drop off funky green.
