90 Toyota 22R 2wd

My father's 90 Toyota pickup's having problems. Starting from the top. A while back the truck started running poorly. I'm not sure when it started. The engine would not rev properly. Like it wouldn't get up high enough. You'd push the gas and it'd just reach an abnormally low limit and it would pulsate up and down some. I know a while back my father rebuilt the carb. Then I guess it stopped working or something cause it was down for a while. My dad then replaced the carberator and then i went and replaced the oil pump. Also replaced the wires, distributor cap, rotor, spark plugs, and determined we have spark. It was difficult to start and when I got it started it ran the same way as it did before but the engine shook more violently and it barely stayed running. We tried to restab the dist. a few times and then I couldn't get it started again. I've stabbed a few more times and almost got it started but I can tell it'll be rough if it does start. Also I changed the oil pump cause at startup sometime the oil light'd stay on a little too long and a friend heard it and told me that was that sound. I'm really stumped and my dad needs my help on this. I have the next couple days off work so I have to knock this out soon. I'm glad somebody is out there who cares. I apreciate the opportunity.

Sounds like a myriad of troubles there.

Where did the carburetor come from? If it's not a Toyota rebuilt or you don't have good skills in rebuilding the original one, some trouble is here. These carburetors are complex and not worth a wooden nickel when they do eventually fail.

How's the timing chain? Known troubles here with this mileage. Who "reset" the distributor? Why? W hat's the timing now?

How's the compression?

Start with my links and posts below and let's go from there.

Okay, the carb is from autozone and i'm not sure about compression. I know the number one cylinder has compression i just don't know how much. Not sure about the timing chain will check. Thanks for your help i'm gonna go work on it and get back to you with a report. Oh yeah my neighbor and I reset the dist. a few times. Finally I read that you determine tdc by burning the crank and sticking your finger in number one. It says to turn the crank and when you feel compression it's the upstroke or something and that's tdc. I restabbed and the leading edge of the rotor is right before the first tower on the first plug of the dist. number one whatever and the direction is correct. Thanks again i'm gonna go check this out.

I talked to a friend who suggested that the valve clearances may be poorly set. He also said the timing chain could be a little loose maybe tdc is not really tdc ect. I'm gonna pull the valve cover and check it out. I've got a chilton's manual(i know i know) that gives hot clearances I was wondering if somebody knew cold clearances or if it has something to do with the table on the opposing page. Thanks.

Check the links below for some ideas, notably www.autolibrary.org.

I recommend a factory service manual though.

1990 22r not 92

to start off the truck is a 1990 not a 92 sorry. okay i pulled the valve cover. timing chain is definately loose. i've started pulling everything so i can remove the timing chain cover to tighten or check the timing chain tensioner to see if it needs replacing. i'm considering waiting till tommorow to get a friend who knows more about the 22R. I'm interested to know why the timing chain is loose and what if any are the consequences.

also when i have the crankshaft timing mark on zero the mark on the cam sprocket is already like at 1 o'clock. i think the mark is supposed to line up with the arrow on the cam housing. p.s. joe, the link to autolibrary has an extra . at the end that makes it not work. but thanks anyways :-)

Your mileage is why the chain is loose.

Pitch all the gears, chain, tensioners and seals for new OEM Toyota parts at this stage of the game. Don't chince and don't gamble.

You don't want to do it twice .

Try looking in www.autolibrary.org for the timing procedure.

Are you using all new OEM parts for the repair? Make sure to change any tensioners if present. They are likely worn at this age too.

The timing marks on 22r are not straight up, the cam mark is off to the right side...like you see 1 o'clock

there should be silver links on the chain, just line up the dots on the gears to be on the link where there is one and between where there are two

thanks everybody. my friend told me the timing chain cover could be removed without removing the head. i've lowered the oil pan some and loosened all the appropriate bolts (i'm pretty sure) it's on there pretty good and i'd like to avoid loosening the head. thanks for all the help. oh yeah the new timing chain came with new tensioners and ect. plus of course i bought new gaskets. although now i'm thinking about a new oil pan gasket too.

almost done

Allright I've done everything. I took the timing chain cover off and changed all the parts. I put it back together and I was close to finishing when I discovered I had left two bolts out of part of the compressor harness. I got one in but the other is being really stubborn. After a long day of this project I'd had enough so I packed it in till tommorow. I'll break it down enough to get those bolts in and then we find out exactly how she goes. I noticed when I had put the cover already and I turned the crank to tdc that the timing mark on the cam was a little behind the tdc mark on the head. When I take the crank a hair (equal to the distance to like 15 or less but going the other way) past then the cam mark lines up. I'm afraid that when I was setting the crank to tdc when they were seperate, the way I got there may have set it off a little. I put the truck in gear (1st) and tugged on the front a little. The crank and cam were now both on tdc. I then put the whole chain assembly on and it fit perfect. The bright link was on top and bottom and the marks of both gears were lined up properly. I turned it and I think they met up fine again. Later they started meeting up wrong. I don't know if I messed it up a bit or not. What do yall think? I'm sorry about how long this msg is but I'm trying to be through. Thanks for the help.

As long as they were lined up you ok. Once you turn the assy the links start moving around. Eventually the will line up again if you turn it enough times

thanks

thanks toyota dude. The problem was the mark on the cam was a little behind the crank. Initially it seemed good. However it's not exact. The crank will hit tdc just a hair before the cam. Read back to my last post for the specifics. I'd really apreciate yall's help. Thanks everybody again.

k it runs good. it still runs just a little shaky though. and every once in a while it hiccups. I thought i'd run a tank through and it'd stop but it still does it. just every once in a while it shudders. what do yall think?
