Talking 22R now goes clunk, clunk, ... IS IT BLOWN OR NOT? Advice welcome!

Hello Pirate4x4,

Recommended Summary:
My shit knocks and smokes, is there any way it's still good?

Background Details:
New here. First post.

After watching it mostly sit for a few months stopped to talk about a FOR SALE sign. Bought a 1984 Toyota 2wd extra cab with 234,000 miles for a few hundred. Jump started it in the dark then drove home. Next day noticed alternator belt was gone so installed one. Oil was off the stick so put in two quarts of 30 weight. After filling noticed over the dipstick a bit but drove anyway (would overfilling with oil cause my problem situation below somehow?).

Drove it a few days and couple hundred miles. Mostly drove well. With one exception: warm idle was rough and too low to stay running. So drove with two feet at stop signs. Noticed would shift from second to third in the automatic at about 70mph when blowing carbon out so ran strong at higher RPMs.

Took to a friend to look at it with the goal to turn up idle. Drove it into his shop. When we took oil dipstick out looking with a shop light could see little puffs of smoke coming out of the dipstick hole and thought gulp. Friend said PCV. We then did the plugs, fuel filter, PCV valve, and air cleaner (noticed oil in the bottom and hoped because of overfilling second gulp). I can blow backward on old PCV by mouth and not on the new one - old PCV appears bad may explain smoke.

I was in the drivers seat when he had me start it for the first time to adjust carb. Idle was low as still warm so had to keep foot on the gas to keep running. He had me take my foot off the throttle and the idle and engine nearly died. Had very very low RPM like the vehicle was hardly running when he was adjusting the carb like chug, chug. Right then my engine developed a new loud "chlunk" "chlunk", ... sound that goes faster or slower with RPM I had not heard before. Very loud like a rod is going out or bad detonation. Gets faster / slower with RPM. We turned it off right away as and did not want to cause any possible further damage engine.

Checked the firing order thinking we made a mistake and it is 1-3-4-2 as it should be.

Then did not know what do do next. Many questions come to mind: Did I throw a rod as have seen that before and is what it sounds like? Could a carb adjustment cause this loud sound? Would one of the plugs is not firing for some reason due to us making an error replacing them? Does anyone know first-hand what a 22R sounds like when one cylinder is not firing (when one plug wire is removed does a 22R make a chlunk, chlunk, sound)?

Do you more experienced 22R people think it can be made to run again even though making bad sound now? It drove just fine into my friends garage before the sound started ...

Could be blown but hope to fix. Have a timing light, digital tach, tools, car trailer with tow vehicle to move it if need to, compression gauge, digital volt/ohm meter, and more. Am experienced working on vehicles so now diving into this. Reaching out for information from those more experienced working on 22R engines is what brought me here. Not sure what to do first and next while plan to share progress and eventually fix.

For now I am only guessing. My plan is do what I know first:

1) compression test
2) leak down test
3) check old wires with an ohm meter
4) replace the cap/rotor/wires.
5) re-install new NGK plugs as seem fine.
6) drain oil and look for metallic parts.

Should probably do if above doesn't fix (have not done these):

7) check timing when not running - this could be a detonation problem.
8) check valves (have done on other cars not a 22R).

Any other ideas, feedback, and similar experiences are welcome.

Ed

When someone buys a used rig and within a few days it sounds like a rod knocking could be funny to some. Will know how funny when fixed. Please stay tuned.

Do a compression test and a leak down test, do not start the motor just let it crank over. Then check timing and adjust valves. It could be detonation. If you want I could come help, I'm in Portland as well.

Thank you JediJesus for your reply and generous offer. May take you up on it as do not have direct first hand experience myself and you do. Could return favor giving a good place to work on yours out of Oregon rain (or something). Will do some online research on your advice and send you a private email to discuss details. We can work on it under cover with light out of the weather here or where at as have access to shop space. Will send you a private message so we can at least keep in touch. It is nice to know another Toyota person in town and glad I posted here. Will let all know if it is a goner or not and expect to be working on it this weekend starting in the morning. Tonight will go out and look for one of my two my compression gauges with fittings as recently moved and not sure can put my hands on them or not and would hate to have to buy a third one for this.

UPDATE: with some other advice that just came in... "clunk clunk developing when adjusting the carb could be more of a knock knock...your leaning the motor out (bad), or you have a loose or broken rod. Smoke out the oil filler or dip stick is usually a good sign of bad rings. Either is a good sign its time to rebuild. Pull the oil pan and check bottom end. Its a good amount of miles. If you can rebuild it yourself it wont cost you that much. She at best needs some new bearings, rings and a good hone job, eh? Thats if you haven't chewed into your crank shaft or don't have a nice ridge at the top of the cylinder walls."

siperman: There is not a Pirate22r.com for Toyota people to share information when the 4x4 and 4x2 have the same engine. Did offer a great link as a peace offering to the over 1000 page Toyota Service Manual for all the 85 Toyota owners here with 22R engines which is something they may like to have if they did not already.

Hottrod81: thank you as yotatech.com is the other BBS I found to try at the same time. Was hoping to get as much info as possible before work on it over the weekend. Found good information and have many ideas on what to try tomorrow including possibly getting the help of a local which is already awesome so at this time when trying both to see where get better information I have to say Pirate4x4.com has had better information so far. Will tread lightly with a 4x2 and will focus only on things I know for sure are in common with 4x4s to add to the community here.

Not sure why, but it's REALLY hard to read and understand what your trying to say...

Maybe next time say something like "My shit knocks and smokes, is there any way it's still good?"

Thank you for the feedback "ssic off road shop" and others. Just re-wrote. Will get to the point and not try to tell a story in the future. Ed

Your shit is knocking, it had no oil, you drove it, you almost certainly damaged a bearing.

The knocking changes with RPM = Could also be wrist pin or piston slap.

Its gotta come apart or just run it till it blows, try some straight 50 weight racing oil.

The fact that it has 234K on it, I would say its just about at its design limitations anyway.

Swap in somethin with more power if you do decide to swap engines, being 2WD makes it SOOOOO much easier.

Look into a 1UZ, already auto (same auto as a matter of fact, A340) and you can get the entire car (Lexus LS400) for $500-1000!!

And its all toyota and reliable.
