Added cats so I won’t stink like exhaust having fun in my toy. They don’t affect “feel” hp wise. Goes along with my techy Megasquirted EFI Jeep anyways.
That's weird...i have side pipe with only muffler....never had smell issues...
Last October while hunting in Colorado and idling hours on end. The exhaust smell would give me a headache. Also, anytime me I drive the Jeep any distance my clothes smell like exhaust and bug me. I’m man enough to suck it up, but old enough I don’t want to deal with it, So, I’m doing something about it. Jeep.....never left well enough alone.
What did I do to my Jeep today?
Towed it 300 miles across several mountain passes. We had a great week 4 wheeling in SW Colorado, now back to the grind.
Edit-a couple of random thoughts.
This was the 12th year that this truck and this Jeep have made the roughly 600 mile round trip from Colorado Springs to the San Juan Mountains. I think the CJ has more towbar miles than driving miles!
Also, this pic was taken at the rest area where the picnic scene from National Lampoons Vacation was filmed....I looked for a hot chick in a Ferrari, but no such luck!
Finally decided to take the windshield frame apart. Got the hinges out...PITA...drivers side lower is the only bad/rusty spot that will need replacing.
Maybe this doesn't count, but I got my earlycj5 sticker in the mail and immediately installed it. (small circle in upper corner of windshield) Delete if this doesn't go in this thread.
^Good looking Jeep
Ever since I fired off the engine I have been unable to get idle below 1200. I was 99% sure there were no vacuum leaks, sprayed the intake and carb base down with cleaner. No change. Blocked all the ports nada. After some YouTube I was almost certain it was the secondary idle stop on the TA470. I pulled the carb to change the screw ( id like to punch that engineer) to a hex so you can use an allen key. Soon as I pulled the carb, there it was. A port in the back of the manifold under the carb. The rubber cap had deteriorated and it was open. Must have been tucked up where the cleaner didn't hit it. Sigh, Occam's razor strikes again. Now all those unused ports have pipe plugs....
And? Does it run better?
Let you know tomorrow, I have to pick up a gasket.
What a great Jeep!
Mom and Dad visited for the first time this year. I don't think they have seen the ol' girl since I put a v6 in 6yrs ago. The rebuilt carb fired right up on the 2nd try and it didn't leak oil everywhere. While it buzzed along We chatted about our old s10 with a 4.3, the k30 with a 305 and later 350. I think they approve.
It was running 210f and 40psi on the oil at 2200 rpm without any carb adjustments. I turned the key off and it dieseled for a while then ran backwards.
Guess I need to lower the idle and check timing.
Hmm. So fixed my vacuum leaks. Timed up nicely, vacuum gauge tuned the carb 17"@idle ( sweet) and then there's this when you rev it up. Gritting my teeth this isn't a rod knock. Even though it's been 30yrs since this engine was built I clearly remember plastigauging the mains and rods on the crank kit. Other than the Rhoads lifters and the whining POS ps pump it sounds good. I'm wondering if the rockers are hitting the valve cover when the lifters come up with the rpm. Sigh, what say ye?
Where’d you find a diesel 231?
My opinion is that is NOT a rod knock. It's a rocker or two loose on their pivots. If they are hydraulic lifters , then that's the problem. Pull the covers , build some oil dams with rags, and try to adjust the lifters by sound .
I was just about to type that
Yea it doesn't sound like the knocks I've heard. This valvetrain is not adjustable and I have Rhoads ( fast bleed) lifters to tame the cam. I'm going to pull the valve covers and have a look. I've got a small valve cover leak anyway. Youth, if it wasn't a pain I'd pull the cam for something tamer.
I hear you, 'Old boy ! So ... the rockers ride on a shaft ? The Rhoads are hydraulic. . Pull the covers , run her, & listen and look. You'll most likely hear & see it . It sure sounds like a bad lifter to me .
