The Grumpy Grease Monkey mechanical engineer.
I've got a 1987 corvette here, in the shop,that had a blown head gasket I repaired, the engines got good compression, and it runs decently when first started and will do so unless its engine is turned off, this is intermittent problem, making it a bit harder to isolate, the engine does not cut...
owning a decent code scanner helps
youll want to own an infrared temp gun and a decent multi meter
Amazing deals on this Zr15S Active Test Obd2 Code Reader at Harbor Freight. Quality tools & low prices.
a couple scanner related tools worth owning
yes a decent infrared temp gun is a helpful diagnostic tool
keep in mind , even if everything running well,
the front two cylinders tend to run a small amount cooler (20 degrees) simply because the increased cooler air flow over the header tubes
the actual exhaust gas and header temp will vary with the combo specs , your looking for consistency not a specific temperature at the exhaust ports
