Plastigauge is not going to tell you if the bearings turned into an oval when you torqued everything down. You have to gauge the entire motor. At Dyno Proven here, they are currently rebuilding some pice of **** Volvo twin turbo motor that jumped timing all over some piece of **** idle tensioner at 80k miles. The hole motor is gauged.

well yes im aware of that, but atleast i know my clearances are within spec so far. new rods, new pistons, new bearings, fresh bore, new main bolts, new head bolts, the motor had 15k miles on it. and just so you know, this isnt a volvo. and what does a idle tensioner have to do with timing? chain tensioner?

Anyway I brought it up because the motor is gauged as it's getting rebuilt. No plastigauge is used. There is also 3 built DSM cars in the shop and all were gauged and plastigauge was not used. 400-500 whp and running for years now.

its only there for ease of mind. better than not doing anything, eh? so you meant the timing belt tensioner went bad on the turd.....well that'll happen. surely it has a maintenance interval for replacement along with the belt. i built the motor for my crx and didnt plastigauge it...had no problems. takin a mic or using plastigauge.....same diff....just making sure you're not too lose or too tight.

so im bout as far as i can go for now until i get my heads together, so now im just waiting on my buddy to finish porting the heads. one head is almost done. so i got the rear main seal put on
the baffle plate
revup oil pump and oil pickup tube
and the oil filter stud for an I30 since im bypassing the factory oil cooler
now im tryna think of what color (if any) that i should paint the timing cover? imma paint the top half of the rear cover since some of it is visible as well. any ideas? wrinkle red valve covers, wrinkle black plenum, black brackets/coolant pipes, maybe just a silver for the timing covers?

so ive got the timing covers painted up in the cast aluminum color. still gotta paint the sprocket covers in black. and i just got in my aem uego twin channel wideband kit. currently looking to use one gauge with dual displays so i dont have to deal with 2 seperate gauges.
and i got in all the stuff for the qx4/pathy coolant bypass mod in as well. as far as the port work...*sigh*....still in progress. one head is one port away from bein done and the other has been started. just itching to get all that mess done! and im still debatin on whether to get the head surfaces cleaned up or not. they are true and straight (unlike frankie haha), but i just want them as clean as possible....idk, we'll see about that. so really the only thing left to order is a new clutch disc. and i got an agency power clutch line ordered too. yay!
