Another Chinese Part Fail out of the Box

Fired my new Blue Print Engine a few days ago. I am using a EFI system with Temp sensor in the head and a OEM temp sender for the OEM gauge in the intake manifold very close to the engine thermostat. Engine fired right up and had its normal out of the box EFI teething stumbles but all in all was running better than expected. I noticed the temps were not syncing between the two sensors. The head kept overheating while the sensor close the the engine thermostat was not indicating it was warming correctly. I had to cycle a few times chasing leaks unrelated to the engine. The temps were concerning. Was it a air bubble, bad tune overheating the head, bad water pump, also new. or what. I finally settled on the new Summit Tstat. I had one in the other motor without issue. Purchased a new HiFlow 180 Tstat from Speedway motors. The engine temp is now rock solid from the first start. It is clear everything must be checked prior to placing in service. What a shame.

I'm not saying this to sound high and mighty. I've only fired 3 fresh engines in my life, and to help ease my worries, I tested the carb(another engine), tstat, mech temp gauge.

I'd also like to state my first fresh engine break in was an absolute sh!t show and took weeks to solve leaks, bad gauges, incorrect cooling fan, more leaks, incorrect timing set from taking bad advice, terrible carb tuning because it had not been tested after i rebuilt it. just a mess

Yes, new engine can be quite the challenge. This was a post fire rebuild. Fire was result of piss poor engineering of a fuel rail on a 8 stack that I questioned but ultimately went ahead with. That fire took out 90% of everything forward of the seat. Other than the tstat the only things I had to chase were 2 tranny cooler fittings not tight enough and two power steering/hydroboost fittings that did not want to take a seat. Not bad given it was a total rewire as the fire took it all out last September.

I put a hi volume aluminum water pump on a existing well functioning cooling system.
More had to be better or something.
Acted like it held the T stat closed kept over heating in a few blocks.
No t stat was fine too
Stock volume pump back on... all my problems quit.
Why I don't know.

Yea working in automotive repair years ago we learned which brands and certain parts to avoid regardless of brand and therefore looking for oem parts. Its gotten so bad now with the conglomerates rebranding parts with a box being the same pos parts being in multiple diff brand boxes but being the same part from a manufacturer if you will call them that. China really went hard on the copying of everything under the sun a quite a few years ago. We have to test everything these days before use.

Back when I pulled the SBC out of my '68 Skylark, I needed a new t-stat housing. Painted it all purdy Buick red and put it on. You know how much fun putting the t-stat on the FRONT of the manifold is, if you've done one. Filling it with coolant, and it starts pissing out of a casting flaw.

I know we all thought the dudes hoarding parts for their vehicles for the incase i may use them own the road were weird....lol here we are complaining about parts now.
