    What does your oil pressure run at? Cold vs. fully up to temp?

    I filed a Product Safety complaint with Amazon today. This kind of crap is going to kill someone.

    What does your oil pressure run at? Cold vs. fully up to temp?

    I wish... saved nothing (paid full price) and got $4,500 worth of damage. Ordered a long list of parts for 200k mile service. All fluids/filters/injectors/sensors.... Missed that the plugs came from Amazon Marketplace vendor, not Amazon. It snuck in under Prime shipping making it harder to...

    What does your oil pressure run at? Cold vs. fully up to temp?

    I’m in the middle of a tear down trying to figure out what’s going on. Found a broken spark plug, 7 melted and several burned exhaust valves. Figured out the plugs were counterfeit ACDelco. Sheeeettt...

    What does your oil pressure run at? Cold vs. fully up to temp?

    Does synthetic oil tend to drop the pressure readings? At temp I'm 42psi WOT, 32psi cruising ane 20 psi idle. Running a Texas Speed 6.7L stroker with high capacity oil pump. Original engine got eaten by Castec heads leaking coolant into the oil and melting the cam bearings.

    Time To Rebuild

    When my leaky Castech heads ruined my 5.3L (about 140K miles) and I started shopping around for what to do. The original block needed so much work that I ended up getting a 6.7L stroker block from Texas Speed in Georgetown Texas, mild cam upgrade and new stock heads. Its an impressive upgrade...

    Fuel Pump Chk valve

    So I pulled the fuel rail with injectors up and pressurized the system and the freaking thing is now holding pressure. Reassembled and is still holding pressure. Makes me think you guys are right and its a flakey injector as the last two times it was always consistently quick drain to no...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    There is a pre-filter in the pump and a replaceable filter in line just after the tank (at least in the L59 flex fuel trucks). The check valve failure doesn't seem to leave you stranded, just you need to move the key to "on" hold for 2 seconds to build pressure then go to "start". Otherwise...

    Fuel Pump Chk valve

    Is there a good recommended spot to pinch the return fuel line in these trucks and repeat a bleed down test? Last two failures replacing the pump fixed the issue. Injector set has 55k miles on them. I replaced the injectors at 155K miles since I was doing the intake gasket at the time.

    Fuel Pump Chk valve

    Got 210K miles on my '04 Tahoe. Truck needs its 4th pump. Pump pressure is fine but after you cut the engine the fuel pressure bleeds off rapidly. What the hell is going on with these AC Delco pump check valves??? I'm getting about 30-75k miles before they let go. Haven't been stranded as...

    LS3 Swap 2003 Z71 Tahoe

    Doing my fluid swaps before some January skiing. I'm with you, a 6.7L on a 5.3L setup is a concern for the tranny and diffs. The G80 gov-lock exploding pumpkin especially. Since hard launches tend to just wheel spin/slide the truck I just don't do it. I got other cars for that stuff :)...

    LS3 Swap 2003 Z71 Tahoe

    I'm using the factory harmonic balancer. Wonder if that was a mistake on my part. Since I'm using a low RPM torque setup vs high rev, its probably not a big deal. The 6.7L motor is the same block - just bored and and different crank/rods/pistons. So everything bolts up. The whole line of LS...

    LS3 Swap 2003 Z71 Tahoe

    I put a Texas Speed 408cid (6.7L) stroked iron block in my ‘04 Z71. Stock heads with STI valves and a mild Texas Speed cam. Texas Speed suggests the LS6 PCV engine valley cover and an external oil vapor recovery system so I put that in. I used the Elite Engineering catch can. Everything else...

    High mileage suspension/steering refresh.

    My '04 Z71 truck has 185K with only the shocks (123K) and steering column intermediate shaft (45K miles) replaced. All linkage grease boots are worse than what you have and a lube job will leak grease out of the cracks. Still no slop in the linkages yet, but that will eventually change when...

    Need help on 3rd row seat latch bracket

    Haven't done this repair yet. Anyone have a line on these set frame striker brackets for 3rd row seats? Might be a good 3D printer project instead of aluminum.

    Need help on 3rd row seat latch bracket

    This is for my 2004 Tahoe. The screws for the rubber coated latch brackets on my 3rd row seats back out and get sucked up by the vacuum cleaner. I'm using M5 - 0.8 x 8mm flat head screws with blue loctite to try to hold them in. One of my brackets went missing. Is there anyway to buy...
