Yep, I learned all about it with my ‘87 mini truck and ‘89 4Runner. TERP-Toyota engineered rust protection. But jokes aside I’m not sure what to use for chassis paint once I finish this messy business.The caked on grime is an excellent paint preservative and antitrust coating.
Not pictured in post #299’s photo, but still essential are the following:Degreasing Continues…
Ok I’ve learned a lot about degreasing engines over the past week or so. There are many truths, but this one stands above all else. You cannot simply hope to spray on degreaser let it sit and hose it off. You will need to scrape off all the dirt. Even spraying with degreaser and agitating with a stiff brush won’t get the thicker stuff off. Then and only then can you hope to spray on degreaser, agitate, then hose off.
So this was today’s approach. I found a plastic putty knife, and a soft bondo filler spreader, which I cut in half. With these two tools I scraped the frame rails, engine mounts, bump stops, and anything flat enough to accumulate greasy dirt. Even after two rounds of spraying engine degreaser and even pressure washing it, the grease was dry underneath when I was scraping.
So just to really dive into some philosophy here there are no short cuts. You will have to cram your arms into the under carriage, do some akward yoga on your garage creeper and scrape the dirt off.
Once I scraped off the thickest stuff i sprayed citrus degreaser (2:1 citrasolve) on one area and used my quiver of brushes to agitate and listen the last layers of grease. If the dirt started to absorb the degreaser I’d spray a small amount on.
Then after I hit several areas with the citrasolve and brush treatment I broke out the extra weak electric pressure washer and hoses off the muck. I modified the PW to make it shorter by removing the wand and putting on a 22mm to 1/4” quick disconnect fitting. This lost 20” of length and made things a lot easier for close quarters.
I’ll eventually post some before and after pics, but since I’m still working on getting what must be pounds of crap off the engine and chassis you’ll have to be patient. So you will have to suffice with a photo of all the essential gear you will need to do this job.View attachment 2803145
Starting at upper left and working clockwise:
More later…
- Garage creeper
- PPE including plastic rain gear, eye protection (highest quality goggles are recommended) and a respirator
- Degreasers and high quality spray bottles: find your flavor, I like simple green, super clean and citrasolve…
- Brushes and scrapers, you will need a variety’s. Bottle brushes, toilet brushes, “tooth brushes” brass detailing brushes, and grout cleaning brushes are all useful.
- Pressure washer with shortest possible wand with narrow nozzles (the one pictured is ok, but even shorter would be better)
- Pistol style hose nozzle
- Good lighting that is also waterproof.
I heard if you buy enough cheap stuff, they’ll shoot you into space!Still shopping at commizon ?
Yea, I was a tad close….but I think what really happened was this:Looks like you’re in that cruisers bubble. It’s forgivable.
Today I had a ricey ford truck with fake chrome covered side view mirrors and fake chrome side fender vents park way up my cruisers bubble. Not forgivable.
It's a great question. I started with the leaky exhaust and looked for leaks above the o2 sensors found leaks everywhere. I replaced the muffler, and every gasket below the Manifold to down pipe union, as well as deleting the PAIR system and relocating the o2 sensors, but the low idle still is an issue.Did you ever figure out the low idle once your rig was warm? I have a 93 and have the same issue.
Thanks! My plan is to replace the vacuum lines as well as a first step. I've read about quite a few people that have plugged lines coming from the EGR system, so I'll probably be taking off the intake manifold off as well and replacing it with a nice clean one I bought a while back, as well as replacing the injectors with new ones that have been sitting on my shelf for a while lol. Then 'while i'm in there', replace the FPR, fuel filter and test the solenoid under the manifold with the spider web of vacuum hoses. Love the project. I'll let you know if I'm able to fix the issue.It's a great question. I started with the leaky exhaust and looked for leaks above the o2 sensors found leaks everywhere.

I suspect that I have a number of vacuum leaks. My current plan is to replace every vacuum line on the truck (many are original) and then see how things are doing. I haven't done a test for vacuum leaks, so I don't know for sure, but I would be shocked if there are not any. Will this solve my low idle? I don't know, but It will solve old cracked hoses and rule out vacuum leaks. The vacuum hoses are pretty cheap. I'm trying to do my homework for the "while you are in there" things, but no doubt i'm missing a few things. Good Luck figuring out your issue, the good news is that the parts for all this are fairly reasonable!
Do let me know, it looks like you're much farther along on the research than I am!Thanks! My plan is to replace the vacuum lines as well as a first step.
