Hello everyone and thank you for all of the laughs and information. I've been a member here for a while and i really enjoy participating in the forum. so...... after giving up on the turd-of-an engine in the burb, i searched for a low-mileage replacement. i found an '85 or '86 660 J-code engine with 39k miles 3 hrs away (this was the summer before last :().


i soaked it in WD-40 and covered it, held up very well. about a month ago i primed the oil pump, lifters, etc and the compression test showed "good" compression on 7 cylinders, one was a little hesitant, yet all 8 reached 400 psi within 6 compression strokes. hopefully a quick valve-lap will correct the hesitation. now given the condition of the engine, some cost factors, and the known main bearing fitment issues.... i have decided to leave the lower end as-is. i wanted to do it up right, but decided (with time constraints, etc) to leave well-enough alone. i also avoided (however favorable) hot-tank costs by plugging and blasting everything.


the engine was blasted white (sorry no pics, 12 hr work days, down to the minutes here) and painted. i have never sprayed with a pneumatic gun or even thinned paint for that matter, however, using my best suite: common sense, i managed to come up with a nice product and had a blast doing it! :HiHi: :bounce::confuzeld that's all for now..... there will be PLENTY of porn and fun to come! thank you, and i am very excited to share this with all of you!

pics...??????

i realize not everything is painted, my focus was the block and heads. btw: engine cost me $200, the only trouble is: the oil pan is shot, valve covers are so-so, oil cooler lines were cut, no wiring and the mounts were destroyed too..... lazy f***ing Ford guy...... POS

the process

well I've made a lot of progress, and suffered a major set-back. after examining the heads I noticed the bowls/ports were actually quite spacious and overall decent, except the horrible taper where the intake mani bolts on. so I began removing the little flash that was in there and blending the end of the intake ports. (the intake manifold also tapers severely as it approaches the head). unfortunately GM machined an unnecessary push rod "relief" (angled, cut into the intake ports). the end result was a large hole in each of the intake ports, the Nickel rod welded it and the heads subsequently cracked near the weld.

lower end

although the compression was strong, the cylinders were glazed, so I tore the lower end down and honed the bores. the timing chain is tighter than new one I installed on the other 6.2 (~1/4" of deflection). everything is like brand new!! :HiHi::confuzeld:bigglasse


the new 2-piece Victor rear main seal did not come with instructions and after hours of searching I couldn't find the answers I need. which flange (lip) the 90* or longer - 30* faces outward? the seal is numbered on one side. also, how do you apply the sealer recommended on the rear main cap? I plan on staggering the ends of the seal with the cap/block faces ~3/8" (carefully pressing the seal inwards to avoid cutting the outer lip).


thanks for the help.

Pennsylvania run

well I located an NV4500 and a supposedly low mileage 6.2 near Lancaster, PA. turns out the 6.2 is a redblock, cast in March, 1981! after replacing the ever-too-readily clogged fuel filter in the Sonoma, iron duke/5 spd, she towed the approx. 1500lbs strongly, I am impressed. it was a long 450mi. uphill journey home. a few hills brought us down to 55 mph at the top, aside from that 75 mph was the travel speed. :HiHi:

Those look sweet. Can't wait to see that motor tore down.

****

thanks, only lost like 2 mpg towing also. just as I feared: the lower-end is shot, completely neglected. the heads have hair-line cracks, if the clean up okay I think I will run them. the rockers are like new though, cast! :HiHi::bigglasse


I've been bed-ridden since Saturday evening. doc says it's a virus. I have never been so ill. I'm pissed right now, could've put the damn thing back together in the time I lost..... :shake: jesus

so I got the heads hot-tanked, 1 is flawless except for minor corrosion in the combustion chamber, the other is the same except it is so pitted it's f***ed.


I also coated the pistons and turbine housings, the cartridges are next.




tons of parts available!

Lapped all of the valve seats, #1 and 3 cyl. had bent exhaust valves????? Dropped in the lower mileage 82 valves .... Good as new.

As long as I do not mix up the valves, can I ceramic coat the valves in the original coated area???? (see pic, lower portion of stem, seat and face). the coatings are shot.
