3.6 Engine Rattle Determined

[viper88]

heck can't you just get an entire 3.6l Penta from a scrapyard for <$2k? My big mistake was not also getting the auto which you can also source for next to nothing from a scrapyard.

You can get a like-new take off 3.6 for $2600 from a company that does engine conversions.

I wish they still had some Jk engines in stock, can’t get a decent price anywhere.

Great post, I've pulled valve covers off a few times. Done a few valve jobs on older engines back in the push rod days. I've done a few timing belts, various side engine sensors under the timing belt cover on Hondas.

What are the "special tools" which hold "everything" in place on the 3.6 Pentastar? If I have a lifter problem after the warranty expires, I'd prefer to repair it myself. I like taking my time on engine work and order all of the one time fasteners which have a long lead time.

Edit: On my Odyssey timing belt job a few months ago every dealership could have had it done the next day. It took me 2 weeks because I waited for the one time bolts to come in. Here is my stack of "extra" bolts, each accounted for. The dealership wouldn't have replaced these with new.

Cheap Chinese plastic crap but it makes the job go much easier. No need to pull camshafts.

We’re putting one in a 2015 Rubicon right now, nearly 5 grand for a reman long block from Chrysler. Price on used low (<90k) mileage is near 4K.

And that’s just the part. Total estimate 9,000 or so.

You ever order from Jasper?

That’s where it would normally be coming from. 5-6 weeks lead time right now through jasper.

Topline started out machining air-cooled VW products. They continued to water cooled VW. In the late 70's and early 80's some Dodge 4-bangers shared the same head as some water colled VWs like the Rabbit. They progressed to remanufacturing complete long blocks for a lot of brands. Today they make high quality lifters. I wonder if their lifters are worth a look for 3.6 rebuilds?

You work at a independent shop or a dealership?

They make great lifters, but I don't think they cover our application...

I did not realize that. Thanks.

Great company. I met the owner Chet when he first started the company. We used to go over to the factory all the time. We got to choose and cherry pick components for high performance builds at no additional cost.

Independent.

In my experience, it’s not the lifters fault. It’s the rocker arm. Roller bearings lock up and then the lifter follows, and camshaft damage over time. Not nearly as hard on the cam as an LS collapsed AFM lifter.

I watched a teardown video on the 3.6 last night. Crazy how much more complex this motor is than what I've seen in the past (small block Chevy, I-6 Toyota). I've never torn down a motor or worked inside one, but I am familiar, and some of the stuff in there is never seen before (oil separator inside cam?).

Also surprised to see that the cam/lifter issue I'm having is so common there's a set of tools to make the work simpler. Gives me ZERO confidence in this engine.

Also super disappointing to see plastic head covers. Im not surprised tho.

In consideration of a new jeep, I was looking at the 3.0 diesel,but it's made by Fiat...not an inspiring engine builder. Sow what are the cost-reasonable choices? I'm not getting a turbo 4cyl and I don't want a hybrid, and I can't afford a 392!

The few I know of and have seen personally were the roller bearings locking up or coming apart.

Cam locking tools exist for every engine ever made. They are an absolute necessity.

Good clarity. Appreciate it.
