It has been buging me that a few people I trust were commenting that this thing was noticably smokey, patricularly at the top end of the rev range. That coupled with what I call excessive blow by even at idle prompted me to pull the engine out.
The bore is quite glazed and scored in places, the rings are similar condition. Not real surprising when I look back at how rich it was running when I first got it. Also, its first oil change showed some very fine debris in the pan... not the shiny bearing type, just vrey fine dust. I guess no air filters will do that.
Inside the motor it was very clean, this thing has not done much work at all. machined and ballanced crank, rods and pistions. The flywheel has been lightened. 5.8 kg combined fly and pressure plate. Metal race bearings, forged rods, hks 272 cams and a host of other goodies. The real surprise is how worn some of the bearings were. just take a look. this is why air filters are so important.
Main caps
#3 big end was the worst
Big ends
lightening in the crown of the pistions?
It is getting power honed, new rings to match, new set of undersize king bearings as the crank needs regrinding, #1,2&5 were particularly badly worn. The clutch is getting a birthday while it is all in bitz. The 45mm Webbers are getting checked, the head is off for a clean and look over/tidy up, a set of ARP bolts are on the way as is an underdrive pully set. Ballancing is being checked on it as well, looks like it was all done in Jp, but I want to know it is right. The box is off getting a service as well and to check the gear set out, there was a chip in the oil when I drained it. I was told it has a TRD close ratio set in it and a TRD 2 way diff... the diff checks out, now I will Know about the box in a day or so.
It will be good to know for sure what is in the the thing and that it is all in prefect condition. I will putting a peddle box in tis weekend so There is plenty of room for air cleaners. I think the remote oil cooler and filter has been piped wrongly, putting backward oil flow through the filter. Something to check out when I get back home.
