I wouldn't say I freshened up the motor. I checked the ring gap, cleaned some parts, and put my used blower cam. This is the second motor I have done the same thing, too. The first was a 90 thousand mile LS1 it lasted 5 years. This LQ4 with 289 thousand miles and roached cam bearings spun a cam bearing 4-5 months after I got it running. If I were to do it again, I would have replaced the cam bearings. The bottom end is 100 percent fine.
I thought your not supposed to oil the rod caps before installing bearings. Only assembly lube on the face of bearings not the rods. Or block. Was always told you risk spinning the bearings but idk 🤷♂️
Oil is going to get there when the motor is running. Idk it's just the way I was taught. As long as you do not have a dry start issue, I don't see how it would make it spin. There are probably a million different ways to do it. I have only spun one LS rod bearing, and that was more than likely from installing ARP rod bolts without having them honed.
How much power can this engine hold on the stock internals I’m just wondering because I have the same lq4 , just debating on if I need to put forged pistons to boost it
There are guys out there pushing a 1000 hp. I would say 600 to 700 is a good safe range with a decent tune and to have it last longer than a few months. It really will depend on the shape of the bottom end and the bearings. This motor ate a cam bearing 6 months later. That was my fault. I should have replaced them cause they were toast, but I rolled the dice and lost a cam from it.
@@FullThrottlePerformanceMike my thing is I don’t know what rods are compatible with the LQ9 pistons that I’m tryna put into my LQ4. Do they come out of an LY6?
If you are going to be using lq9 pistons just stick with the 3rd gen rods. I'd you are using aftermarket pistons you can get a set of floating pistons that will work with the 4th gen rods. But now the rotating assembly will need to be balanced.
@@FullThrottlePerformanceMike I was going .10 over and either way, so yea ur right balancing is inevitable.The motor is getting built with either machined 317’s or 243’s, comp 54-469-11 cam, and beehive 26918-16 valve springs. I’m not sure how much the 3rd gen rods can handle, but given that I was trying to up the compression a bit I thought gen 4 rods should be good for 500 whp
@CIA my Ls1 with the ctsv blower was around 600hp for 5 years or so before it spun a rod bearing never had an issue with the 3rd gen rods. But the 4gens are better for sure mostly from the floating wrist pins

Great video! I like how you keep it cheap and simple for this video.
Thanks. In today's world cheap is all I can barely afford.
Great video with some good tips.
Thanks man
5:18 my truck is the same way. Driver's side is tar like and passenger's side is clean
So after talking to a bunch of people this is common with a high mileage motor or a plugged pcv valve.
@FullThrottlePerformanceMike oh yeah I'm at over 460k miles lol
@@lacboiatl nice. They really do run forever!
Subscribed bro
Thank you
The pcv valve is on the drivers side bank bringing in alot more deposits
It sure does. I just had never seen one that dirty. After doing a little research, I found it to be a common issue on the lsx base.
So you basically refreshed the motor. How long will this motor last on boost. Makes me want to do the same thing to my junkyard LQ4.

I appreciate it man I’m new to the Ls game and I’m learning as I go bro
@wiseram9270 no problem
I have a gen 3 block with gen 4 internals and all new bearings ( main and cam) how much can I hold stock
So what gen rods and what pistons were used? I’m currently building an lq4 so just looking for pointers
That was all stock 3rd gen stuff. But if you are using stock parts 4th gen rods are the way to go.

Thanks, maybe?
Bout how I disassemble things...
