Who, other than H8PVMNT, has honed cylinders in prepping a 20/22 block, and rebuilt it yourself?
I do if the cyls haven't been machined. I have done three 22's and a 7mgte, no issues with the engines I still own. Honing isn't rocket science.
As you know I have done this a few times. I have an old hone I have used every time I did it and I never had excessive oil consumption when I did. I think it has provided a better job than when I have used what the machine shop has sent home with me, to the point that I might start running it over newly prepped blocks before assembly. I will see if I can find out what Ra it is.
I’m just trying to figure out what, exactly, I should know and what you have done to successfully get the compression and the low oil consumption where it should be after break-in on a rebuild 22.What honing tool did you use?
What manufacturer of pistons and rings did you install?
What Ra did you end up with?
How did you measure the Ra?What piston to cylinder clearance did you measure?
UPDATE: March 17, 2019Since 2 cylinders (3 & 4) had good numbers on the last compression test (155 & 150), and considering that none of the exhaust valves were sealing, I’m now leaning towards installing the new head and see what happens. If the severe oil consumption goes away, I may not pull the engine down to re-rebuild it at this time.
I know you do your research, Why are you considering using a felpro head gasket?I have witnessed on several occasions, felpro head gaskets lasting 6 months to a year. If you look at a felpro gasket next to a toyota gasket the quality difference is obvious.
Based on the exhaust valve issues with the head, that is all I would do, your only out the cost of the head gasket, head inspection/machining, and your time, if there was more issues than just the head.
I have done a few head gaskets on 22R/RE engines. I have yet to see a Toyota head gasket fail prematurely.
I have had 2 "OEM" head gaskets from 22re performance and they were both TOTOTA brand. So they are in fact OEM OEM.
another vote for 22re performance. i bought their kit when doing my top end.compared to the gaskets from engnbldr it was a no brainer.I did use felpro on my fj40.....but that had a 327 CB
If money isn’t a factor in the decision, then I am completely baffled why it’s not an obvious choice to use Toyota OEM gaskets. If you have another failure using any other brand you’ll be kicking yourself. Toyota has a long and successful history with 22R-E engines.
Yeah man!
If this fails I'm willing to come down and pick it up. I have one last Boy I need to outfit with a Toyota truck, Yours would be perfect.
Which head gasket is which in your pictures?What is slipper plate style?
