I'm BLUE Posted September 19, 2012 Report Share Posted September 19, 2012 Oak Leaf :rofl: Old Ford I6's are great engines ! 7-main bearings ... I'm wide-eyed by the bearing size selection made available for these lol Even the Fuel Injected I6's up to 96 are long living engines... I've rolled in bearings into 1 of them after jacking up engine... pulling the pan ... BAM ! pretty straight-forward I personally think the bearing's take a beating on that long of stroke/what the bearings look like afterwords ( wear pattern , but most look good ! ) Even the famous ford start-up "rattle" is so universal as many people that own them mention it lol ...yet the fuckers keep going lol Seen the I6's with high miles keep rolling and driving !

Theres a guy down the road with an 86' with I6. Hes going on 400k on original engine. A few years back the hg blew and I helped him do one of those crazy three part flush repair deals and it worked. He drives it every day. Quote Link to comment
I'm BLUE Posted September 19, 2012 Report Share Posted September 19, 2012 I believe the 400k !!! Things won't die ... Most mileage I have personally seen is 363k .. MANY over 250k All started/ran/drove/stopped Quote Link to comment
Dat Lurka Posted September 19, 2012 Author Report Share Posted September 19, 2012 The engine in this thread is at 227k When I do the rebuild it will probably come out to a 2.1 because it really really really need to be bored. I expect it to someday be a 2.4 with 1,000,000,000 miles. Quote Link to comment

Dat Lurka Posted September 19, 2012 Author Report Share Posted September 19, 2012 I just recently noticed the coolant lines running down the inner fender well. My KC used to be an Automatic. I wonder how many miles are on the 5 speed. I wish it still had A/C <_< Is anyone running one of those generic A/C kits in a 620? Quote Link to comment
Dat Lurka Posted September 20, 2012 Author Report Share Posted September 20, 2012 I'm picking up a 1969 L16 with 69k this weekend. It's been sitting an estimated 15 years and it turns trough without a problem. It's a long block but everything else is in a box. The best part is I'm paying what it will cost just to get the head done on the L20b. I assume it will bolt in no problem. Oh, and it has a finned valve cover B) When I can afford to build the L20, the L16 manifolds will be a replacement for the crap L20 smog ones. And I assume the l16 will get better fuel mileage than the 226k miles L20 Quote Link to comment
bananahamuck Posted September 20, 2012 Report Share Posted September 20, 2012 L20b ..6 bolt flywheel L16 .. 5 bolt flywheel and if it sat 15 years the head gasket will undoubtedly blow if not replaced. Quote Link to comment

I expect it to someday be a 2.4 with 1,000,000,000 miles. To get to 2.4 liters you would have to bore it out until the pistons touched. There are no 95.25mm L series pistons. Realistically you might bore an L20B out to 89mm... (2,138cc) But that's 1.5mm off all the way round the bore. Cylinder walls are getting thin... Quote Link to comment

Why should the headgasket be bad from sitting? It's already a long block. I can swap out for the new headgasket no biggy. To get to 2.4 liters you would have to bore it out until the pistons touched.

datzenmike Posted September 20, 2012 Report Share Posted September 20, 2012 Well you said bored. When I do the rebuild it will probably come out to a 2.1 because it really really really need to be bored. I expect it to someday be a 2.4 with 1,000,000,000 miles. You can get to 2.3 with KA or Z24 pistons and Z22 crank/rods. The Z24 crank won't fit without lots of cutting, then you need a really short rod/piston to match. Quote Link to comment

flatcat19 Posted September 20, 2012 Report Share Posted September 20, 2012 Why should the headgasket be bad from sitting? It's already a long block. I can swap out for the new headgasket no biggy. Coolant gets acidic over time. Hell, coolant more than 7 years old on a daily vehicle will even eat a block, head, water pump, radiator, heater core, thermostat, and hoses alive. Add in the fact that it is a 15 year old plus chemical compound. Newer coolant's don't do this quite as fast as older coolants with a different/inferior chemical make-up. If someone was to plan on letting a vehicle sit over time, it would be wise to drain the coolant. Iron blocks rust. Aluminum heads will go through electrolysis. Head gasket will get eaten. Better safe than sorry. Quote Link to comment
Dat Lurka Posted September 20, 2012 Author Report Share Posted September 20, 2012 Not to mention the materials of those original headgaskets. Quite similar to the coconut backing on the seats :rofl: Quote Link to comment
Dat Lurka Posted September 20, 2012 Author Report Share Posted September 20, 2012 HEY what do yall think of the L16? Quote Link to comment
flatcat19 Posted September 20, 2012 Report Share Posted September 20, 2012 Good motor. Rock what you can. You're not really in a place known for Datsuns. How much are you getting that L16 in a box for? 720's should be abundant in your area. Cruise the yards for a Z22 from a 1981-1982 720. Go from there. Quote Link to comment

Go from there. 170$ shipped halfway. 720s are all rusted out and rednecked to hell. The only nice ones are the diesels. There's a decent amount of 620s. A few 210s. And as many Z cars as anywhere else. I'm leaving this shithole ASAP and going down south to take care of a few things. Then I'm gonna make my way west. And pretty much so I can play with more datsuns. and the weed. Quote Link to comment
flatcat19 Posted September 20, 2012 Report Share Posted September 20, 2012 170$ shipped halfway. 720s are all rusted out and rednecked to hell. Who cares the 720's are rusted out? Wait! You do. The motor's will be fine and newer than that L16. I'm sure you can find a Z22 truck motor for the cost of that L16. Your freshly rebuilt cylinder head on top of a Z22 motor makes for one hell of a little ripper! LZ? Yes, please. Quote Link to comment

If I can find a z22 for 100$ then yeah that might be possible. Head job's gonna cost 100$ It's gonna cost me just under 200$ to go get that L16 But I'm sure I can find a good Z22 for less than rebuilding the L20b. So my U67 on top of a Z22 will make a pretty sweet 4 banger? that's an option for the future Quote Link to comment
flatcat19 Posted September 20, 2012 Report Share Posted September 20, 2012 Call a salvage yard. Ask. If can find a Z22 for less than $200, pull the trigger. What makes you think the L20B needs to be rebuilt anyways? 1 Quote Link to comment
Dat Lurka Posted September 20, 2012 Author Report Share Posted September 20, 2012 Not a z22 anywhere around me and one z24 for 550$ Quote Link to comment

Because it has 226k miles and the cylinders are so worn the the pistons sit to one side of them :rofl: Last I checked the rebuild without timing kit is 221$ Quote Link to comment

Price of oversized pistons if your kit doesn't have them. Bearings for the rebuild need to be bought/sized when block is being machined. New timing kit. This can go on for a while. Adds up fast. For the price of a correct rebuild, you can go KA. Quote Link to comment

It will need to be bored. Timing is new. With the kit and machine work it will still be under 400$. I wouldn't go KA that defeats the purpose. If I wanna go fast I'll go get my roadster and put an R1 engine in it B) Quote Link to comment
