Radiator leaks and Overheating

I own an 04 runner, 4.0 sr5. I have put 2 radiators in in the past week, both have failed at the same place. Driver's side bottom near the drain valve. First one was my bad, bought it from Amazon for cheap and made it maybe 20 miles before leaking and heating up but stopped truck before it reached the red and had it towed. Second was from Napa and made it a whole 200 miles before the dripping started. I am interested to know why this is an issue for me and if it's common.

Background: No it's not a gasket failure since I did 3 block checks a few weeks ago and they all passed. Thermostat works. Water pump works, water is circulating through the system and their aren't air bubbles. Not leaking coolant and not overheating either. Just very very VERY frustrated. Love my truck it's my baby but I'm hating it right now. Every week (LITERALLY) it's something new that goes wrong that I have to fix. I'm seriously considering selling it and buying something else. Very depressing

Car started -ran-wont start next day

I have a 2002 lincoln sedan. It has a small nick in the oil pan and was leaking oil. We went away for a month, came back and wife took the car to the store about 6 miles roundtrip. The oil idiot light came on an the way home. Engine was not knocking, no unusual sounds on drive home. Next morning she told me about the oil light. I checked the oil and it didnt register on the stick. I put 5 Quarts oil in next morning and car will not start. It will not start but did turn over slightly. Battery appears good and does not require jump (I tried it). Looking under the car I noticed oil running out and it appears mixed with water.

2004 Buick LeSabre engine noise

I have a 2004 Buick LeSabre with a 3.8L V6, with 159,000 miles. After changing plugs, oil, filters last Nov. the idle speed dropped to what I guess is about 600-650 rpm. It started to make a high pitch squeel, intermittently, on deceleration (only at mid level engine temperature), like the belt was bad, changed it and still there. Changed idler pulley, still there. Live in Buffalo and wasn't going to deal with it in the winter unless I had to. (took a trip to Virginia and it never made the noise) This spring at inspection, my mechanic swore it was the belt, but didn't have time to do it. I changed it again, noise still there. Went back to him and he tried to tell me it was an engine mount! The noise happens almost all the time now when you come off the gas, when mid to full operating temp. Now does it in park at 3/4 temp, then stops unless in gear coming off the gas, stationary or moving. I used a regular stethoscope and it sounds like it is coming from the timing cover, or, more likely the cam area. Incidental - A/C clutch was not engaging until I added freon, super stop leak, freon (not staying cold, but, clutch engages) noise never went away! Do you think it could be oil pressure to bearings? Would changing oil weight help? Oil pressure warning NEVER came on, and so far performance is not affected. Any ideas?

1999 cougar 2.5 v6 a/t

Description of Problem: 1999 mercury cougar 2.5L V6 automatic trans: I was driving down the road and suddently lost power. the engine was still running but sounded alittle rough so i turned it off. then it wouldnt start. after having it parked for a couple months i started looking ant it and notice that the starter is spinning the flexplate but the harmonic balance isnt turning. it does turn by hand with a socket. after talking to a mechanic i was told a used motor would run $1500+. he said i broke the crank or timing chain? i thought if it was the timing chain the harmonic balancer would still turn, he didnt agree. and i thought it was unlikely that the crank would just break driving down the road. Do you have any idea what it could be? or how i can narrow it down. not alot of autoshops where i live and the one shop im pretty sure just wants my money cuz i dont know much about the problem. if the flexplate or bolts broke off would that cause my problem? Any help or advice would be great thanks.

Car idles rough stalls in any gear

When the car is in park it idles a little rough like it's going to stall out. Whenever I place the car into any gear it stalls out immediately it was running fine early today then I thought maybe it was low on oil, so I put a quart of oil into the vehicle. Then I check the oil levels and the dip stick is covered in oil. As if there is too much oil in the car. When starting the car it sounds like a diesel truck, will idle at 1 RPM, then when placed into any gear the car turns off.
