@iamdub I forgot to credit you with making me first start googling oil pump porting yours looked great which led to this I just didn’t feel like doing the inlet I think it looks okay from the factory.

I did get the motor torn down and everything looks great so far except I broke both spring compressor tools I had. I’m not sure if I was using them wrong or I’m just an ape, anyone have a better suggestion I can get in 3-5days?

Not sure where you can get one that fast but this is the type I use. It works extremely good, really necessary if you're doing dual springs.

Wow that’s cheap, I was looking at a comp cams one for like $100 it’s super nice and does two springs at a time. I think I’ll fork out the money for it since I can get it shipped asap

Lmao I did all that in about 3 hours with a buddy who’s got five broken vertebrae just chit chatting with me. Non of it would be possible without a good knowledge of these trucks and a few key Milwaukee tools. First is the two M12 ratchets they are amazing time savers, the impact helps a ton as well as the hood light!

They make the same design in a double but I find it easier to concentrate on one at a time. Both my trucks have double springs and it takes all my concentration to do one because it’s hard to keep the stem centered as you’re compressing the spring. Vinci High Performance turned me onto this design, the others don’t work well on double springs.

I’ve got a ton of scrap including some thick stainless from my welding class so I’m gonna try something tomorrow for sure.

Alright, I'm a social media influencer!

I've never seen a compressor like that. But, I might've found a use for that Comp trunnion kit I'll be removing from them rockers.

Can you bite that block portion on top with some large Vice Grips and use that as a handle?

My brother uses the one that does both springs at the same time. Idk what brand it is though. If I were getting one, I'd get one that can do both. So much faster

Frustration level 1million today, tried multiple attempts at making my own compressor but it wasn’t happening. I tried using one of the broken aluminum ones by grinding an extension down square and running it completely through the tool. Only to have it break the extension, and vice grips weren’t enough to hold.

I ordered a comp cams tool after a buddy recommended it and said he’s done multiple sets of dual springs with it.

Also tried to measure deck height and my comp cams timing tool set didn’t have the right setup to set the dial indicator up over the piston so I think instead of spending another $50-100 I’ll just throw ls9 gaskets in it and call it a day.

I also can’t get the crank bolt out although I’m the one who installed it and it’s an arp bolt. The big daddy Milwaukee didn’t have the balls while using a wobble and extension and iirc the last time I did it I had the whole front end apart so I could get right to it without any attachments to the impact which would explain why it’s extra tight now. Not sure what I’m gonna do I even tried my 3’ breaker bar and another 3’ of pipe but it didn’t budge. I’m letting it soak overnight with creep oil.

I just used one of these, Mounted to one of these.

Used a straightedge across the cylinder and brought the piston up until it touched then verified by sliding the straightedge across the piston from the deck. Then I set my dial indicator on the piston, zeroed it out, and raised the piston until I got the maximum reading. Rocked the piston at the max height and got my number.

I have both those and the magnetic base is acting up and not being magnetic anymore. Not sure why or how that breaks. I suppose I could but a new one for $12 I didn’t realize they are that cheap. I’m just cranky from failures, I couldn't even get my new/used push mower that I engine swapped to activate the self propel transmission! :bawl:

6’ of pipe. On a different day. :)
Did you use the ARP lubricant on the threads when you installed it?

I can't imagine that I didn't use it I'm pretty good about that stuff. I'm gonna fix my Milwaukee charger and put my 8ah battery on it so its fresh and then can vibrate that ***** right out.

Hope you get it broken loose man. I hate when things don't go as planned. Sometimes, its best to take a break for a bit and then bam, it works good.

That big boy milwaukee should do the trick...if not, put some more d*ck into it. You'll get er
