Just finished this repair last night. Jim is the best and his instructions and these videos made the job a breeze. Just make sure you keep the chain tight to the crank sprocket throughout the entire process. It doesn't take much slack for the chain to skip a tooth. Jim is there to answer any questions through the process and the ratcheting tensioner is top quality.

Fantastic, betweeen the 3 videos 15, 16, 17 i was able to do this job. Starts and sounds better now, and runs way better. Couldnt have done it without these videos, and Mr1jims fantastic responsive emails with so much detail, it was like he was in the room helping! Definitley reccomend doing this if you have any start up/driving rattle. My 1992 hardbody pickup does not have AC /AC condensor so i just took the rad, fan and the grill out and had tons of space to use my full size drill, and be 100% confident on the hole location by seeing it straight on from the front. Take your time, watch these videos multiple times and refer back while doing the job and its very simple. I also highly recomend the rachet tensioner that Mr1jim Sells and shows. Its defintley the best option and absolutley worth the extra little bit of work. I was surprised, once I started and pulled a couple things out of my way, at how simple the whole thing was, provided you are very cautious not to let the chain slack. Have a few sizes of bunjee cords at the ready before removing the cam bolt. You're the MAN Jim!

Thanks Justin, Amazing how strong these KA24Es run when valve timing is being held where it should be. Glad it smoothed out the low power band in the low rpm range, its always nice to have an energetic peppy engine.

Seems to make swapping this crap FAR MORE difficult than need be ¿Maybe it makes the block stronger? Idk but it’s crazy!!!! *second side note* I’ve owned 3 d21 with the z24 & they seems to be bulletproof!! I never did anything to them other than change oil … in the last 10-15years I can’t count how many d21’s (here in Georgia) with the KA I’ve seen for sale with *blown motor* My thinking is I bet every KA catastrophic engine failure was due to this tensioner madness!!!

Hi mr Jim. Do you know if the tensioner can be replaced without that plug? I have a stanza and the frame rail doesn’t allow the hole to be made.

No it can't. We have attempted to remove the tensioner in a D21 with out the access hole. The tensioner fasteners can be loosened and turned out but they hit the front cover before they free themselves completely of the threads in the engine block.

I am not familiar with arraignment of engine and that frame rail, wonder if there is a modified short profile hole saw or drill motor that could be used. But then you would still need to get a socket in there to get at the fasteners.

I just replaced mine without the plug. It is not easy and I wouldn’t recommend it without the oil pan being off just in case you drop it. The 2 10mm bolts will not come all the way out, which causes the problems when trying to get it out. But with the help of a few extension magnets it can be taken out with the bolts still ran through the body of the tensioner.

Could be a number of items? Might be related to TPS, MAP, and or the MAS, these three sensors work with each other, if one is faulty, it could cause the others to send incorrect fuel mixture or wrong distributor timing at the wrong rpm range. Which could engine to stall when rpms are changed or if power is demanded from engine. Not a sure thing but worth looking into because these three sensors could cause condition you describe. You should be aware that the TPS is a variable rheostat and needs to be calibrated when installed so if it has been removed and not calibrated this could be the cause. Don't remove the TPS unless you have an ohm meter to calibrate it, which will need to be done when you do the re-install.

@jamesmartin5370

@@clutchcrusade It needs to be calibrated with an ohm meter. Its just a basic a rheostat. it sends a variable electrical voltage to the computer as the gas peddle is depressed. As the throttle butterfly valve opens the voltage increases and the computer reads the voltages from the above three sensors mentioned, averages them and then adjusts air to fuel mixture and distributor timing as needed. So when a new TPS is installed it needs to be set with an ohm meter before snugging down the fasteners. Once the old TPS has been removed, unless you made some type of index locating marks, even the old one will need to be set before the computer will be able to make correct adjustments to the air, fuel and distributor. This needs to be done before you can move forward with any more meaningful trouble shooting. No big deal, will only take several minutes to do the job.

and sometimes, there's no start up rattle but instead chain slapping at 1800-2500 rpm... no rattle at idle, none at start up, nasty 'tween 2 and 3 grand rpm though, nasty sounding like God's fingernails running down an metal chalkboard makes my hair stand on end every time horrid horrible horrific sounding.

Yes, If engine is shut down with the valve springs putting pressure on tension side of chain there will be no start up rattle. If engine is shut down with the valve springs putting pressure on the slack side of chain, this pushed the tensioner piston into its bore and there will be start up rattle. Start up rattle is dependent on if valve springs are putting forward or back pressure on the cam shaft. With the chain being so long in these they need the guides to control chain oscillation at different speeds.

@@jamesmartin5370 have you ever run a KA24E with a ratcheting tensioner without the outer guide in place? Wondering if it would work or not because I was advised to delete the outer guide by a random mechanic who is a KA24e owner... Did so and now the chain is rubbing in a different place at higher rpms. Bad advice maybe? wondering if the advice was wrong or if, with the ratcheting tensioner that would maybe negate the need for that guide. Or not. Anyway I'm about to find out... Going to put a shimmed piston in and see if that helps run without the guide at mid level rpms. My experiment was to find out if random guy was right or not.

@@hehunches Running these engines without a chain guide is Bad Advice. I would not do this. With these overhead cam engines, the chains are long. They need a guide on both side of the chain to prevent the chain from oscillating. It will damage the timing chain cover, maybe even cut a hole through it. I know someone who tried this, the outcome was not stable and he ended tearing it down and installing the guide.

@@hehunches Before you put it back together. Inspect the timing chain for excess slack. Rotate engine until the tension side of chain is tight, this is the side with the straight guide. Then look to see how much the tensioner piston is sticking out of the tensioner. If it is sticking out 3/16" of an inch or more this is too much slack and you will hear the chain at start up. The slack can be adjusted out of the chain using an adjustable piston with shims, but keep in mind, this is a manual adjustment, as the engine gets more hours on it the sprocket teeth and chain will wear and the slack will come back and another adjustment will be needed. The self adjusting ratchet tensioner is self adjusting so it will self adjust as needed always keeping tension on the chain, its the better of the two methods I know of right now.
