    What would cause fouling on just half of the spark plug?

    Im very happy to report that after installing Fel-Pro intake and valve cover gaskets, my engine is running great. I still need to drive it for a while and then will check spark plugs to be sure. I can already tell after the first test drive that it’s running much better with improved throttle...

    What would cause fouling on just half of the spark plug?

    I was finally able to get the top of the motor removed. Here are some pics. I noticed a couple of places where the vacuum leak could be coming from: - intake bolts above cylinder 1 didn’t have washers and show some rust marks, the distributor gasket had a break in it, the intake gasket had a...

    Here we go

    It’s sort of like cleaning out the garage. Get everything completely out so you have a clean slate to work with. Instead of all your junk in the driveway, fill up the truck bed with the interior parts. Then clean it up really good with a vacuum and broom, it will gross you out what’s been under...

    Here we go

    I was intimidated by redoing the interior, just didn’t have any experience. As it turns out, it was much easier than I thought and parts availability are plentiful. Kind of expensive but soooo worth it. The little lady doesn’t complain about the ‘stanky old people’ smell and will ride with me...

    Very cool, that probably won’t fit a 12.50x37 but I’m sure I could make one.

    What would cause fouling on just half of the spark plug?

    That’s exactly what I’m going to go with. Do you have any suggestions on RTV usage, the little China Wall rubber pieces and such?

    What would cause fouling on just half of the spark plug?

    By the way, here is a pic of my truck in its current configuration. I’ve done a bunch to it over the last couple of years, I’m a tall guy but engine work on a truck with a 6 inch lift and 37s is not easy!

    What would cause fouling on just half of the spark plug?

    Ok, I spent the evening putting everything back together. I did the vacuum test to check for a leaking intake gasket by plugging the valve cover holes and the PCV valve and plugged in a vacuum gage to the dip stick. The results were 4.5 inches of Hg vacuum at idle on a cold motor. I’m sure when...

    What would cause fouling on just half of the spark plug?

    Here is what I got after doing my first compression test. It looks pretty good to me, correct me of I’m wrong. So, rings and valves seem to be OK if I understand correctly. I am now leaning toward an intake gasket leak. This motor came with no intake and I installed one. I got a little...

    What would cause fouling on just half of the spark plug?

    I really appreciate all the suggestions, I'll run the compression test(s) tonight and advise.

    What would cause fouling on just half of the spark plug?

    Thanks for the replies. I will read up on what a wet/dry compression is and make that happen tonight. Is it OK to do a compression test with the rocker arms, and valve cover off the #3 cylinder? Will anything fly off (like push rods) while I’m cranking? Does that valve seal in my pic look good?

    What would cause fouling on just half of the spark plug?

    Ok, now I’m not sure what I should do. I installed all new plugs and within 100 miles it started running really rough again and consumed about a quart of oil. I ordered some valve seals thinking that was my problem and got the tools together including a homemade air chuck welded to the bottom...

    What would cause fouling on just half of the spark plug?

    Unfortunately, no warranty. I bought it from a private seller off the local digital marketplace. The original motor died and I was in a hurry to get it running again. That’s a great suggestion on the inspection camera. I’ll do that and post the pics.

    What would cause fouling on just half of the spark plug?

    Would the leaky stem seal(s) cause oil to be on all the threads of the spark plugs? Although virtually new, this engine sat for a long time. I believe it sat for about 4 years in a garage, before I got it - is that sitting around what could make the stem seals go bad?

    What would cause fouling on just half of the spark plug?

    I was having issues with my newly installed “Hecho en Mexico” base GM Goodwrench engine. I’ve put about 1500 miles on the truck since the install and it was missing and running rough. I pulled the spark plugs after double checking that the timing was at 12 degrees and found that number 1 was...

    Scores from DIY Parts Yards, Pull A Part, U Pull It etc

    I’ve been hitting the junk yards for many years now, with lots of good finds but by far this is the best score ever. Ranger III torque splitter overdrive from Advance Adapters made in 1994. $129, rang up as a transfer case. I happily laid in a puddle under a motorhome in the junkyard to get it...

    Let’s talk about headliners

    I just replaced my headliner. I used the old board as it was in decent shape. I spent time getting all the old crud off the board so the glue would have a solid surface to stick to. I used 3M 77 spray on adhesive from Lowe’s. I used a whole bottle which felt like too much but I’m glad I did...

    What have you done to your square lately??

    All new body mounts. Check out the old and new mounts and bolts. Glad I changed those original 1986 parts out!

    Adding a Suburban Gas tank

    I also wanted to do this to get additional range as I like to explore remote areas. Additionally, I’m setup to fuel dirt bikes or generator or help someone with some gas if needed. I learned a lot and also absolutely love having the additional range. I now have 65 gallons of capacity with the...

    What have you done to your square lately??

    I got it from Rock Auto. The actual fit is fine, it’s just the whole idea of attaching it to the original dash. Sandwiching the two together just isn’t ever going to be neat and tidy at the margins like a new dash pad would be. I even removed the old vinyl from the old pad with a heat gun. It’s...

    Where does this wire go?

    Does anyone recognize this plug? Seems to tee into the wire powering the cigarette lighter. I’m not sure what it goes to. If anyone recognizes it, let me know. Everything seems to work fine.

    What have you done to your square lately??

    I spent some time freshening up the interior on Ol’ Blue. The little lady was complaining about the ‘musty’ smell that was probably coming from 35 year old carpet. New dash cover, seat cover, carpet, Retro sounds full system with 5 new speakers, amp and subwoofer, killmat sound deadening, custom...
