Albert, I too went with Hardi however with P/N # 14424 which is set at ~0.22 bar e.g. 3 psi. That used to be listed on the Prokschi web site but now I see the 18824 listed which is closer to 5 psi pressure average. No issues so far at temp or elevation. I believe at one point in time S-Tec also was ...

Yes, approximately a 25% drop in barometric pressure. Y'd see the same percentage drop on a Pressure gauge not just a 4 PSI drop -- I wish, as it would be a lot easier motoring up in the Sierra's :// Some even push compression ratios up to 14:1 if they operate @ high elevation -- and "ping" free wit...

Ah good catch on the altitude !! Wow, 8,000' feet.
That has to be in the ballpark of ~20% reduction.

Well at 100 psi you have good cause to to do a top end job. You are indeed in a pretty good center of gravity of Pinzy owners and expertise e.g. Linden Engineering. Someone might jump in and perhaps recommend a shop for Head rebuild and jug boring if needed. You really want someone with Pinz experie...

Burnt and appears recessed. Probably was running lean.
It would be wise to assume more than #4 is in need
of a rebuild. Or...you could roll the dice on #4 and hope for
the best -- what was the static compression on 1,2 and 3?

Were you located?

Can you post a picture of that valve. A pix is worth 1000 words

Somewhat vague recollection, but I do recall I wanted to strip it down
to expose the internal contacts then decided not to. Could be a crimped
enclosure and I did not want to break it. You may find that disassembly
is easier than I recall.

The replacement flasher from SAV does exhibit some quirks. It is not the classic bi-metal flasher but it does exhibit a load dependence as you have observed. That is, you rear LED is ON but no flash. That is likely due to insufficient current draw from that one LED lamp with a lack of additional loa...

And this is why I avoid buying anything Smittybuilt. They flipped over to Chinese manufactured long ago. Just don't trust CN made products you have to trust your life with. As of ~3 years ago Superwinch was acquired by a holding company. IMHO that's usually the kiss of death, in fact late 2019 some ...

It's a possible mis-alignment issue. The Bell housing has two
bolts that go through the Starter mount. One with a capture
nut on a separate floating member. If misaligned you will
have to pull the Starter again.

Therefore, I recommend doing the Starter last.

If you are observing oil leaking along the seam of the Cam Housing (Housing between the rear of the motor and Bell housing), the housing seal may be failing. Both my trucks were leaking a wee bit of oil along the Housing seam. I have removed and resealed the Housing on both trucks now -- recently on...

Even pricier still are the extinguishers from H3R Performance. I have a pair of their 2.5 Lb MX250R's in the 710K. But went with Amerex in the 712. Fire extinguishers were one of the first pieces of equipment I put in both trucks along with a complete First Aid kit -- perhaps another tread on that t...

With respect to registration, I had no problem getting my 73' 712M registered in the Bay Area. This truck was a Vineyard Princess and was never registered before. The one thing I had to do was to get it weighed. Now, that said, the DMV can be a bit unpredictable. My recommendation would be: A) lowes...

Wait till your on the trail and find you can flip the lockers ON
and shift the X-case on the fly while moving. All very simple
but incredibly well engineered where it matters.

I'll add $0.02 to the discussion. As an owner of a 710K and 712MK.. As far a inside temp goes, my K is far cooler than the M. But that's by design. My K is Tan not Swiss Green, as Vince pointed out re-paint the roof. A two tone with a Desert Tan top looks OK. Next is noise. My K is insulated, top, s...
