    Pinging under power and drive train Q's

    I though I would do an update. I drove around without the stat for a while and my heat problems seemed to lessen. It is still running about half way between the mark and the red, after mixed driving. It is no longer builing any more heat on the highway in fact it usually cools down a tiny amount. I am still just running the distilled water with just a little bit of antifreeze that was in the block. Still considering a new Radiator or maybe switch to electric fans. I was at the parts store the other day getting the oil change stuff for my Mitsu and got a Mr Gasket 160 High flow stat. so that is in the truck now. I will post any other things I do.

    my 521 is backfiring now ? what could be causing it?

    What Mike is saying is, guys this is a dead post! The person is no longer even here probably. The original post was made 2 years ago. Just some fun at Charli69's expense. Happy 4th of July 521'ers

    Since it's been backfiring a couple years now I say "if it's not backfiring it's not running" don't even worry about it LOL

    I think I did a compression test prior to installing it. I don't remember the numbers specifically but they were all about the same. I do have my other L20B that i burned down the head on so I could have it rebuilt. Since the heat symptoms were the same for both motors and the L16 I think it has to be the rad I found an aluminum one I can afford on ebay for 117.00. So when I have the truck back from the alignment shop I will most likely buy it. I think I am going to go with 2 row so that i have the room for a condenser later on I really want to get A/C in the truck, as much as I am driving it, or just sell the 521 and the 620 and the 3 motors and 3 trans I have. and buy a truck something with 4 doors or an extended cab and air. But as much as I complain about the 521 I am probably too bonded to it now to do any of that.

    datzenmike This is number one after driving around all day and the gap change racerx I agree it looks to be running lean so what do you do to the stock Hitachi carb to fatten it up? I could be also that it is just running hot and that is why they look that way like Charlie69 said

    I opened the gap on 1 from 30 to 40 thousands see if it cleans it up tonigh. 103 here today still not "overheating" but it is still running hot 1/2 way between the line and the red, at least with the thermostat out when I turn it off and start it again in the valves don't chatter

    I tested it on the stove started to open at 179 full open at 188 closed at 174 Unfortunately it did the same thing just took longer to do it plugs are NGK BPR6ES 7131 Kind of wish I had not f'ed with the idle it stuttered and died a couple of times today. I will get it right again following datzenmikes post here http://community.ratsun.net/topic/43745-how-to-adjust-hitachi-carb/

    I will but it gets pricey until I get this figured out, not running it for the long term, plus there is some residual green stuff still in there. Forgot to pull the stat this morning like I told you guys I would, it is out now. I have been fiddling with air fuel but i am pretty sure that is just for idle. I am carrying the timing light with me. I am not sure the fan is pulling very well though the rad. I set a walmart box fan in from of the dam thing and it got cooler, maybe I need to get the fan deeper in the shroud or the shroud further in to the engine bay. Stat is out though as I am typing it is idling in the yard a lot warmer today here in puckerbrush KS. So if it stays cool with the stat out then what does that mean I have tested the stat on the stove it is doing what it is supposed to do?

    CLR had very little effect I did get some flakes out of the radiator I assume this is Calcium or some other mineral build up. Combed the fins, Today I pulled the Thermostat again. I started running distilled water during this diagnostic period, since I have dropped the fluid so much, 89 cents a gallon is less than even the cheapest antifreeze

    Pulled the radiator (in the rain no less) I can verify it is a 2 core Right now Radiator is front down in my bath tub and filled with CLR. I have some medical gloves rubber banded over the upper and lower radiator hose openings radiator cap is on I have the drain cracked mainly to let any gasses out. Should I flip it the other way tomorrow to make sure the engine side core is submerged in CLR too? I am going to straighten any of the bent fins while I have it out their are not that many but I figure every little bit of cooling I can get.

    Okay, so today did the swap on the water pump put the L16 four-blade fixed fan back on it with the shroud. Drove about 15 miles around the city at highway speeds it did not go up to the red like it did previously so I was pretty happy thinking wow we finally made some progress. I checked all the other fluids everything was fine pulled the valve cover after getting the truck up to operating temperature checked all the gaps they didn't need adjustment. Put it all back together. Went to go pick up my old daddy take him to the grocery store and get some tacos in it now it is running warmer than it was without the shroud and the old fan, about halfway between the Middle Mark and the red all the time. Before if I let it idle for a while it would get down close to the middle mark, now it will not do that. I looked inside the radiator while I was working on the water pump swap it looks pretty good in there doesn't seem like there's any build up but of course I can't see down inside of the whole thing. I didn't do the CLR, I thought I would just try it with the swap first, so it looks like that's my last option now. Maybe it's time to switch to an electric fan or something, else. Did this post on my phone so apologies for the format.

    I used a flush product earlier in this process for the whole system. BlueDevil Products 1 Quart Radiator Flush. followed the Deep clean instructions on the bottle drove it around for 6 hours I used premixed O'Reilly Green 50/50 Antifreeze So I did not add any water but i understand the reasoning behind the the distilled water, don't want any calcium or mineral deposits to stick to the cooling surfaces. So Is the CLR still something you think I should do? or is it redundant.
