Thanks I will look into it.

Hi all, getting close to installing my new Optimizer motor. What are you guys putting on the fire wall in the engine bay? I’ve seen the Dyna Pad product but I’m looking for something a little thinner and that it would stick to the wall and handle the heat. Thanks Gus.

Thanks guys, the firewall inside the cab has the factory insulation still intact. I think if I do anything on the engine bay side it will be thin not like the factory stuff that was on there. I do need help sourcing the grey 2 1/2” thin foam tape that goes on top of the firewall inside the cab...

Yes, I was thinking about doing that. Did you notice anymore noise or heat inside the cab without the insulation? On the other site it was mentioned that gassers get a lot hotter than our diesels. I thought it was the other way around. Thanks.

Hi all, what is everybody using for firewall insulation? I gave up on finding an OEM replacement. I wanted to check before install my engine. Or should I not even worry about about it. I imagine these motors put out more heat than gassers. I also have the dash out for repairs and there is also...

Hi all, starting to wire up my glow plug harness on my Optimizer build I got from Quadstar. My 95’ factory harness has two fuseable links one for each side installed in the two large orange wires before they branch out to the eight blue wires going to theGP,s. And why does the left bank side...

Working on a couple of issues on my build. Anyone ever had one of these oil pump drives apart? Going to use this one for an oil priming tool for these engines. I was going to grind the cam gear down but didn’t want to jam metal shaving in between the gear and housing. Also...

Thanks Will

Hi all, now I’m working on the steel return line in the engine bay. Unfortunately I destroyed part of it. I did see the return line kit from Quadstar. Anybody ever used it before? I did see a steel one on Real 4wd,s site I believe it’s for a Hummer. I thought I could...

Hi all, trying to source a crank sensor for my build. Since AC delco a made in China what is a reliable sensor to buy?

Hi all waiting on some intake bolts for my new GEP 6.5. And found some markings on top of the block. Not too worried about the stamped numbers. But worried about the engraved date😩

Thanks spdgofast I found one one eBay $85 😂 ouch

Spdgofast sorry to butt in but did you ever find that vacuum pump bracket ? I need the same one.

Yes I have seen that diagram. I do not think that’s for my 95’ DS4. It shows the one hole clamps on the edge of the valve covers. I believe the one hole clamps go on the lines under the intake. TSP that’s goof to hear that the four threaded holes in the heads don’t go into...

hi all, getting my 6.5 back together. Trying to figure out injection line mounting. I should have to pic,s of the lines before disassembling. I found a diagram on line for a DS4 injection line mounting. I went ahead and attempted to mount the lines See photos...
