Separate names with a comma.
Actually, I think it goes from front of engine block to throttle body or something. The water pump connector has more pins.
Ooops, broke the wire connections on the plug going from the front/middle of the engine block to the water pump motor. I think this connector...
My thought was that combustion in #1 was incomplete, caused by inadequate misting of a faulty fuel injector. Maybe unrelated to the compression issue?
The photo above is the cylinder head with cylinder 1 being on the right. Exhaust valves in the other cylinders are whitish gray. Any ideas on what...

[IMG]Not sure whether I mentioned this but in addition to the polished cylinder wall sections, piston 1 had white deposits on the valves while the...
Please elaborate on how bent rods could contribute to this problem. I did observe 1 and 4 at TDC and 2 and 3 at TDC when the head was off. They...
Camshafts are not yet installed so all valves in the motor are closed. Normally, leakdown tests are done with a piston at TDC on compression...
Head was resurfaced and vacuum tested. Coolant was leaking into cylinder 4 making morning startup rough.
I put the head back on and did a variation on a leakdown test. Since I don't have the leakdown test kit, I inflated my 2 gallon air tank to 115...
I figured out at least part of the coolant/oil mixing problem...sort of by accident. I was getting ready to put the cylinder head back on and I...
Those of you who have been recommending Toyota parts might want to start patting yourselves on the back. I have received my 3rd set of Felpro...
12 volts (12v) is scary. Think about it. 12 months in the year and only one contains the letter "v". 12v...scary.
I watched a YouTube video today showing how to remove and replace the hybrid battery cooling fan. The guy removed the rear seat and panels as...
I think when I get the bolts back in I'm going to test cylinder leakdown with pustons at the bottom of cylinder. This will eliminate the...
It looked to me that there were 2 bolts holding the rigid pipe on. I probably have enough small extensions that it will work. Now tjat the head is...
I have on occasion used a tap but I also hear that can damage threads sometimes. This time, I used a head bolt with grease on it and a small slit...
UPDATE: I'm hoping the head gasket can be seen in this post. It's pretty much the same on both sides with fluid (oil and coolant) distributed...
Next time i do a head gasket on the Prius, or any other car, I'm doing a cylinder leakdown test and a cooling system pressure test before I even...
Just to clarify my original post, I never suggested or at least I hope I never suggested that loctite be put on any threads that are screwed...
