3.6 Pentastar Rebuild Video

[WILDHOBO]

I would how ever have used assembly lube not oil for the beginning start up . It's tacky and thicker

I completely agree. I had the same question. But I’m no engine build expert, so maybe there is a good reason.

I have a feeling since he was doing a "charity case " motor for someone else he wasn't to worried about being 100% correct he is more of a tear down guy than a builder anyhow.

It would drive me nuts to tear down, confirm failure reason, and then just stop. I’d want to put it back together in working order. But I have mental problems.

Most of us Jeepers are mental.

I will do this when it comes time. Woe cant set those Cams on metal surface ?? Wow!

I wouldn't worry about sitting the cams on a metal surface, I have placed hundreds of 3.6 camshafts on a metal table in the shop and used them after reassembling the engine. The thing that will ruin these cams is allowing the tone wheel to come into proximity of a magnet. When that happens, the camshaft sensor doesn't get an accurate timing signal to send to the PCM.

Makes me want to build an engine.

Cool, I have a couple of 360s, a 401 and a 343 here to rebuild.

I'd not mind going through a 4.0 I have here as well.

Yeah, you can. I've done many dozens - including in my own. There's no reason you can't set a cam down on a steel work bench. The lobes are hardened, you won't hurt them. Just don't ding the bearing surfaces, don't make a nick that results in a bulge of metal anywhere, but you can certainly put them on a steel bench.
The trip to your shop is harder on cams and crankshafts than what you do laying them down somewhere.

Depends on how long it's going to sit before starting. If it's going to be a few days, or longer, yeah. I do use assembly lube just because then I'm SURE it's got a layer of protection.
I always prime the oiling system before starting anyway.
My neighbor and I have started using STP as assembly lube.

You can't prime a 3.6 in this way by spinning the pump, but you can still pressurize the system and watch for oil to be where it's supposed to be. Below, the blue line goes to my oil pressure gauge while i spin the oil pump. Got oil running over all of the rockers, through every push rod. I built up 50 psi spinning the oil pump by hand.

So for my future reference how is this hand priming or pressurizing done on a 3.6 seeing that it is driven by the chain on the crank.
Please give me a tip ..I will probably need this information..

Something similar to this. Might have to make some adapter for the 3.6, but if you can access the oil galleries in any way, this can help.

with legacy engines, you simply make sure everything is 100% ready - fuel, ignition, timing, anything you can set, is set and ready, so when you crank it to start it, it's not being cranked long at all and it will start almost instantly.

Thank you for that !

Commie Virginia cares.
Down my way you can strap a Blackhawk engine on it and nobody cares.

Your vehicle must meet Virginia's emissions inspection requirements if it is garaged in one of the localities listed below:

• Counties of Arlington, Fairfax, Loudoun, Prince William or Stafford
• Cities of Alexandria, Fairfax, Falls Church, Manassas or Manassas Park

Inspections are valid for two years and may be obtained by having your vehicle inspected either by:

• Driving past a RAPIDPASS on-road emissions testing site.

Don't tell nobody this. but i just get my registration in a county that doesn't do emission testing so they don't ask. I'm not waiting in a Fairfax DMV or have some joe stick some tube up my gals tail pipe. I'll keep my truck unmolested thank you.

I've fully rebuild motorcycle engines, 318's and 340's. It's a nice feeling driving/riding around in a vehicle that has a engine that you have rebuilt.

I love that we live in a county without inspections. Even though I haven’t messed with the engine, I’d never pass.

I drove my straight piped catless true dual Tundra while living in Alexandria VA for a year. I just registered it at the DMV in Stafford county cus it was close to where i worked. They didn't ask to see any emission testing and gave me my registration and plates. 5 year set too. Didn't know Fairfax/Alexandria had emission testing till my good two shoe aunt tried to get her old mini tested and it failed. they slapped a sticker on the thing and said it couldn't be driven legally till corrected. Didn't realize how lucky i was. dodged a bullet there.

Even unmodified engines with some age could easily fail. My penance is that our other two cars are ultra good on emissions. One PHEV and one EV. So if the Jeep isn’t perfect, we’re still way ahead of the curve.

I did take my Tundra to fredricksburg to get tested. See what it was actually doing. They let me pay an extra 10 bucks to do a test that couldn't be counted against me or put on record. Sitting in the lobby listening the the other patrons groan and complain as the tech redlined the piss out of that truck. Bout Damn near rattled the windows off the building. I could barley keep from laughing when he let off and it just backfired like 4 successive 12 guages. Thought a couple of em were gonna hit the deck and need a change of britches.
