Failed PCV Valve On Magnum 5.2L V8 - Possible Cause of Pinging
Вставка
- Опубліковано 11 гру 2015
- Here's some info that may be helpful for those who are diagnosing a pinging issue on a Mopar Magnum V8/V6 engine in a Dodge Chrysler or Jeep. Sometimes, PCV valves can fail open, causing a vacuum leak through the crankcase, sucking oil into the air intake, causing the engine to run lean (and run hotter) with pinging/spark knock. I still have a little bit of pinging, though it has decreased substantially since replacing the PCV valve.
Holy 7 year old video man! ... but it helped me today. 👍
PCV is a good place to start. I usually use the aluminum plenum plate from hughes engines with the steel shim gasket and indian head or aviation sealant on the lower plenum. It fixes a lot of issues. Also , putting some brillo pad in the valve cover baffle helps.
pcv valve can definitely cause problems, mine in my 95 5.2 dodge ram was very old and gummed up, I feel sorry for the truck honestly since the previous owners didn't take very good care of it, I've done a full tuneup plus just changed pcv valve to an oem mopar one and the truck accelerates alot better now after the pcv valve and seems to idle smoother, my pcv hose has a bit of a crack in it I need to fix though. These 2nd gen ram trucks have a fond spot in my heart, I went through a string of very junky used cars before the ram trucks...the rams even with their little quirks have been the utmost reliable for me for getting from point A to B.
Nice, helpful video. When I changed the pcv valve in my Dodge 5.2, I also bought a new crankcase breather too. (That was the device you showed at the start of your video on the rear side of the other valve cover) Those have filter media inside them and can get clogged up over time as well. It is also not expensive and easy to install. I also replaced both hoses as mine is a 1998 and they were dried and showed some signs of cracks. Safe travels.
Good looking out. I think that's my issue. Thanks for posting.
Thanks. I have knock at idle and smell oil burning. I'm gonna check this. Thanks
thank you for this video
Yeah. Looked down into the plenum with throttle body off. There wasn't an obvious plenum pan gasket leak. Just from an ancient PCV valve. Replaced it. This 1993 5.2 V8 Magnum only has 191,000 miles. Ready to replace the plenum pan with the aluminum Mopar one when it needs it.
Boy that pcv valve looks like a microguard made one. That one broke in half when I hit a bump in the desert cruising around 3 to 5 mph
I had OVER 380,000 miles on my last 5.2L.before it was ready to die from low oil pressure.
What kind of oil were you using? Tell about preventive maintenance please!
The engine in this video now has 311k on the clock. Runs great.
The other vacuum leak in chrysler products is the check valve for the hvac.

What is the part number for that valve cover groment for the pvc?
I'd like to know they pointed me to the help section. way to big ! claim that's what the computers say 👌
Just wondering if you can give us a pinging update on your 318. Or 5.2 which ever you like to call it. Ive got a 99 that diesels or pings i guess when i smash the gas pedal. Ive replaced the pvc and it quit for a week or so then started up again. Maby i need a new one again.
What is this pinging you guys are talking about
@@TalesoftheScales detonation
Great video. She still going
Yep... has 321k on the clock now!
Can I just block off that line and be dome with it and put a filter on that valve and block off the vacuum line?
I wouldn't recommend that.
@@cubecompmtdx If the pcv is blocked pressure will build in the crankcase and the oil will be forced out through the seals and there will be oil all over the engine
Looks llike a PCV395 from MicroGaurd. $3.95 from Oreilly's
My spark knock gets bad on my 360 after I idle for 10-15 minutes. Taking off under a load, it sounds awful. I'll change mine tomorrow and see what happens
Mine does the same thing, love to know why
@@sheilacoolidge5864 I changed my idle air controller and it helped quite a bit but it still sounds clangy after I idle for a while.
Lol, idk why im on my wifes google account, i cleaned mine to brand new while back, easy to do, worked on my caddy also..im thinkin it might be the natorious plennum gasket, but i think its bn replaced already, cant complain, had a tenant die suddenly, so his daughters sold me his truck crazy cheap, $500. 900 in new tires 3months b4 he died getn out of truck, professional lowering kit, airbag suspension, remote cd carousel, towpackage, rims, frontend grill bling, ect,ect..guess he cared bt truck more than them, anyway, 100 in tuneup, oil change, iv put 12,000 troublefree miles on it in just 6months, st 10mpg, lol.still better than my hotrod bmw 540i. Id drive to eastcoast tonight, lots of gas money ofcourse, lol..i drive the shit out of it, everywhere..it has been really good to me.....got my money worth i think, im not picky tho, i own 6 v8's..expedition, dodge ram quadcab, cadillac fleetwood brougham, bmw 540i-m sport package with some legit mods, factory and aftermarket, and a 22ft stingray speedboat with chevy 427. It gets 3.5mpg, lmao..and nextweek take ownership of a 34ft fauxal airbus with v10 i think..im partial to the older cars..and i love this old truck, added matching A.R.E canopy and bed slideout kit and kayak racks..id rather work on my cars than make payments, thanks for the input, ill keep reading these forums
I figured out my pcv went bad after I already changed my plenum gasket and put the aluminum plate kit on it.
Was the old gasket blown?
@@cubecompmtdx I didn’t notice any failures, but I replaced it anyways since i already had it apart. Then noticed oil on the hose going to the pvc valve
My brother put a 360 magnum in a 1984 Dodge pickup. He keeps blowing the plenum gasket. He even made a plate to try and fix it. Last time it was good for 3 days and it blew again. He refuses to blame the PCV. He says he unhooked it and it’s open to atmosphere. Do you think it could cause the problem?
@@Ian-of9oi I’m not sure. But the plate I ordered was 1/4” thick. I’m not a mechanic by any means lol. But after the plate and a new pcv I knock on wood haven’t had any problems out of the truck.
@@DanielThomason thanks for the reply. He made a plate but has done nothing with the PCV. Trying to get him to acknowledge it could be it. He’s a bit stubborn.
Clean the original pcv valve with gas . If you shake the valve and hear the ball dinging it's good .
Or maybe just get a new one for a few bucks
Not necessarily. The spring gets hot and looses its tension. Then it doesn't seal correctly and blows straight through both directions.
Garbage motors. Every single one lasted over 300k and truck body rotted away. Chrysler should be ashamed.
Wouldn't you mean garbage truck then? My jeep has no rot, has 315k on it now and runs like a top.
LoL engines lasting over 300k are garbage?
@@joshgrigsby7097 think you missed the sarcasm :)
yeah you need to wash your underside to prevent rust
