Sick 2F ... Head Gasket?

[jasharp]

I drove to the gas station! And all around town, through the stop-signey part; temp holding steady at "half." I will try to get a real gauge this week.

Its starting easier, idle may be a bit low? The vaccum lines are in good shape but today i replace a few of the rubber caps for the delete stuff from the desmog. I also took out one of the VCVs the po had left on that wasnt in the diagram. Also I think I saw somewhere 10deg is recommended with desmogged 2F instead of 7deg. I might try that too.

Thanks for all the advice guys, you helped make it easy!

Mine runs at 10 or 11 degrees....when it runs.

I had a re-curved dizzy, and ran it at 7. Any higher and I got knocking. Just play around with it to find the sweet spot. (That's what she said)

UPDATE:

Short-short version: I had previously been running 180deg. thermostat, I am now running 190deg. thermostat (part no. 90916-03052.)

I have confirmed with my new, mechanical gauge plugged in to the thermostat housing where once was a temp sensor for I guess smog stuff that was in my case plugged. It bounces between 195 -- 189ish with normal driving around. I got a hint once the new gauge was installed and I was burping it again, and the tstat did not seem to be engaging at 180; I went and found it's box in the trash.

while it was drained I put a new sender for the dash temp gauge in at the back.. now it reads even hotter! like 2/3 or 5/6 al the time. It was a cheap one I got locally. If I understand correctly, they are both just reading the water so they should read the same right as long as flowing? I feel much better about having the air out this time, I used a long skinny funnel in the radiator filler, like someone I found on mud (cant refind the pic.) Hopefully it is just the new sender. "Half" on the gauge like it read before jives with what others have said when going from 180 to 190.

Far as that goes, this thread seems to indicate that 190 is correct and what I want. I guess im paranoid about heat and the head, and Ive not really pushed it yet. 180deg. is 90916-03014; weird that this table at man-a-free calls 190 "cold climate spec" and lists 180 for pretty much every LC ever.

Otherwise, all my vacuum lines are re-sorted, running well, still hard starting when cold. So maybe not. Before it was always very easy on cold start. Sill a bit of poking around to do. . .

the main 60 forum has many threads about problems with the accuracy of the OEM gauge. Temp readings can vary 10+_ degrees depending on where you are taking the reading from. Generally speaking the engine without A/C on should run approx around the temp rating of the thermostat. With A/C the temp reading will be approx 10+ degrees over the rating of the thermostat. Under long periods of load the engine might see 210F or so maybe 215... but once the load is reduced or the a/c turned off the temp should then come back down to the approx range of the thermostat rating.

With a desmogged engine it would seem to me that 180F would be fine for the thermostat, I don't think there is any benefit in running 190F thermostat on Carbed engine, but nothing wrong with it.

I am going to be doing a valve job on the Gazoo. Any additional pointers would be appreciated
