Quick update:

I went to the Dyno day yesterday, but with some mixed results.

I think I am having an issue with the head gasket, no oil contamination, but the coolant hoses are getting pressurized and it looks like I have some dark substance in the coolant tank Sad

It does not seem to have perceptable loss of power, seems the same as before. I also seem to be leaking from the heater core, I have a drip of coolant under the car near the transmission.

On the way to pick up my son the trans started to slip a bit in fourth gear...more on that later.

Got to the dyno shop and J-sauce was the first up. Dyno operator made acouple of pulls and he was only getting around 175 hp - runs were taken in 3rd gear. The operator made runs in 4th gear and his readings went up to 350+.

When it came time to my runs he could not figure out how to get an rpm output, I didn't know so I suggested to clamp on the tach cable, but that didn't work. Angry

Where is the correct point to measure RPM output?

So he made a run in 3rd and was low on the output, so he said he needed to be in 4th. I told him put in D and go. He says is down shifted and wasn;t going to work. I told him to wait until 60-65 and floor it.

He made his run, it sounded mean and not much smoke. He said it got up to 120 MPH. My HP reading was only 171.xx - That does not seem right to me at all. It may have been the trans slipping or something else. It could be correct, but I have some doubts. I don't know if the operator completely pressed the accellerator or if some other factor played in the low reading.

I will post the printout tomorrow, the graph looks good though it climbs steady and plateaus and keeps straight until you let off the accellerator.

Disappointing day to say the least Sad
