Chiquidrac Posted May 14, 2014 Report Share Posted May 14, 2014 Hi Guys, My son just saved a 521 from the junk yard in Colorado and now is sitting in his house instead of in pile of scrap. The truck seems to be in good shape overall except for the engine. We knew this before we bought it so now it's time to deal with it. Our plan is to get a running L16, 18, or 20 and replace the original one. After doing that we want to see if we can rebuild the current engine to have a spare since we have a 510 in the family. So we are looking for help with 2 things, 1.- Does someone have a running L16, 18, 20 available? We live in Northern Colorado. 2.- After we do the swap we will start working on rebuilding the current engine, where is the best place to get the rebuild kit for this engine? Thanks in advance, Here is a picture of the truck. <a href="http://s1329.photobucket.com/user/cheperamos13/media/521%20Pickup/DSC04893_zps14213ffb.jpg.html" target="_blank"><img src="http://i1329.photobucket.com/albums/w543/cheperamos13/521%20Pickup/DSC04893_zps14213ffb.jpg" border="0" alt=" photo DSC04893_zps14213ffb.jpg"/></a> 1 Quote Link to comment
datzenmike Posted May 14, 2014 Report Share Posted May 14, 2014 We have a policy that anything wanted to buy or sell must be in the classifieds. There is a link top middle of every page. I can't believe this gem was at the wreckers!!! Most auto parts stores (such as NAPA, Rock Auto, etc.) will have rings bearings, gaskets and seals for the L16. You may have to buy the rings and the bearings separate. An L20B will also need a flywheel as they are 6 bolt and the L16/18 are 5. The 6 bolt flywheel comes drilled for 200mm, 225mm and 240mm size pressure plates and clutches. Doesn't really matter which size you get but the release bearing collar has to match which ever one you find. If by chance you manage to find a 200mm flywheel the collar on your L16 will fit it..

Tristin Posted May 14, 2014 Report Share Posted May 14, 2014 You may also want to check and make sure it's an L-series in there. If I remember correctly, the 69 was the transition year from J to L; it could be either in there. That truck looks way nice... Especially for the wrecker. Glad you saved it. Edit: you did say you had a 510 so I'm going to bet you know what the engines look like. Just want to double check before you buy wrong parts. Quote Link to comment
flatcat19 Posted May 14, 2014 Report Share Posted May 14, 2014 It says 1600 on the side. Do you have engine shots? Quote Link to comment

Chiquidrac Posted May 14, 2014 Author Report Share Posted May 14, 2014 Sorry, I will post the WTB engine on the classified, and yes it is a L16, here is a couple of pictures of the truck when we found it http://i1329.photobucket.com/albums/w543/cheperamos13/521%20Pickup/20131001_112538_zpsfbf9757c.jpg,[/url] and the only one I have of the engine so far, I will try to take some more tomorrow The engine is stuck, I even tried turning the pulley's bolt with a socket and a big wrench and it will not move, so I am planning on taking the transmission down first and then try it again.

flatcat19 Posted May 14, 2014 Report Share Posted May 14, 2014 Pretty clean. Really good start. Maybe add a few drops of miracle oil to each hole. Quote Link to comment
datzenmike Posted May 14, 2014 Report Share Posted May 14, 2014 Not an L16. Look just behind the dip stick at the top edge of the block just below the head. The engine size will be stamped there. Use a wire brush if you have to. It's an L20B motor. These things are all over Cali If you have ever had one you would know how sore and bruised your hands will get. 1 Quote Link to comment
flatcat19 Posted May 14, 2014 Report Share Posted May 14, 2014 What gave it away? The EGR valve? Quote Link to comment
datzenmike Posted May 14, 2014 Report Share Posted May 14, 2014 Fuel return line and the dizzy cap is too big. and the BPT valve.... for the EGR Quote Link to comment
Chiquidrac Posted May 14, 2014 Author Report Share Posted May 14, 2014 Thanks guys, I had this pic that made me think it was an L16 but I will check the engine tomorrow to make sure. Quote Link to comment
datzenmike Posted May 14, 2014 Report Share Posted May 14, 2014 That's what the factory installed 44 years ago. Sometimes you do what you have to to keep your Datto alive. 1 Quote Link to comment
Chiquidrac Posted May 23, 2014 Author Report Share Posted May 23, 2014 Hi Guys, I finally got a chance to work on the 521, here are some pics of the engine Taking the engine out and I need help figuring out the size of the engine, here is a picture of the side next to the oil stick, I don't see any other numbers on the block. Is it a L20? And finally as soon as I released piston #4 I was able to turn the pulley, so I am assuming piston #4 is stuck for some reason. Any ideas? Thanks Quote Link to comment
mrbigtanker Posted May 23, 2014 Report Share Posted May 23, 2014 Look at the top of the block on the right side by were the head would mount for engine size. Quote Link to comment
Charlie69 Posted May 23, 2014 Report Share Posted May 23, 2014 Look on the block in the location of the red rectangle. Engine Model is the block closet to the firewall the other block is the serial number and if it is the original motor both numbers will match the VIN tag on the firewall. 1 Quote Link to comment
banzai510(hainz) Posted May 23, 2014 Report Share Posted May 23, 2014 a leveler will help alot getting that engine back in and th trans needs to get lifted as its a bitch to get motor back in as the oil pan hits the steering bar. if trans lifyed to max and maybe remove the water pumps everthing clears. I also put the engine mpunts on the fram then slide the motor in to the mounts. I see you pulled the mounts off from the fram then up. read everthing on olddatsuns.com tech section Quote Link to comment
Chiquidrac Posted May 24, 2014 Author Report Share Posted May 24, 2014 Ok I found the numbers, it is a L18. So now I will start the search for the internal parts at rockauto and other places. While I do the work on the engine I will check if I can fit another engine on the 521 bay, I have access to a 1600 roadster engine, an A14 with a 5 speed tranny, or a Z20 1981 510 wagon with a four speed tranny, I will take measurements to see which engine will be less work to install. Thanks for the help guys. Quote Link to comment
Tristin Posted May 24, 2014 Report Share Posted May 24, 2014 The Z20 will be the easiest if those are your only options. What's stopping you from just rebuilding the L18 and putting it back in? Quote Link to comment
Chiquidrac Posted May 24, 2014 Author Report Share Posted May 24, 2014 The reason is that I have never done a rebuild before so I am thinking it will take me a lot of time to do the research and get it done. The good thing is that there is tons of info here so I am confident I can do it, we'll see. Quote Link to comment
EastBay521 Posted May 24, 2014 Report Share Posted May 24, 2014 it isn't hard at all to rebuild.the hard part is taking the motor out and putting it back in. Quote Link to comment
banzai510(hainz) Posted May 24, 2014 Report Share Posted May 24, 2014 Ez to rebuild most stock is just stock unless pistons are bad. cant you get it running now? those other engine swap aint that ez!!!!!!!!!!! Its ot a bolt in a Lmoto will be the ezest Quote Link to comment
