I found out part of my problem today. I went to take the timing cover off of the truck to see if there were holes chopped on it. No holes but some of the bolts were loose, go figure. Not my fault though I didnt put it together. So the other problem to figure out is : why is the coolant being blown out of the radiator when I crank on it?

sounds like a head gasket.
when cranking it over pressure builds in the cyclinder and goes to a water passage via a blown head gasket

YEP, ..... regarding 'it happens more than you know' part, ...not the 'people just don't tell you', ...I DO hahahaha.

I did EVERYTHING I possibly could to make sure the thing went together flawlessly, Zach,....and still, within 3 minutes, ... 'climbing temps, up and down, overflow bubbling, then cooling down for a second, ...then heating up again, suddenly MUCH steam from the pipe..... POOF, HG, in brand newly build motor by a guy who DID do a great job machining it for me to put it together...... tore it down again and slapped a new HG in in one 24 hour period.... (EFI), ...voila, new HG, this time, .....no leaks, GOD WILLING AND THE CREEK DON'T RISE, ...it'll stay that way!

Sorry for rambling, ....the HG leakage causes INCREDIBLE pressure to back up and compression to go down, .... thus, it leaks into the cylinder and ALSO, BACK into the water chambers it just came out of (due to more pressure against the leak(170# in the Hole being created, 13# in the system or so?)....and it can EASILY push it right back through the return pipe, water pump and or right back into the radiator.

We inspected METICULOUSLY upon disassembly and reassembly, ..... NOTHING stood out. Cleaned even more vociferously than before, ...... needless to say, ...it worked out SO FAR! I had an old stat that was partially opened from the get go, ...used that to break in the HG and get it to seat this time, rather than the newer one that seemed to take till 195*+ to open. BTW, .....The first time, ...used straight water........... that also might have caused issues due to the LARGE amount of metal in the OEM HG, ...who knows. This time, coolant, 60/40, .....not a drop.

PS> Again, sorry for going on, but just want to share;

1. IF, indeed, you did blow the HG. QUICKLY get it apart and soak up the water, rust, and then reassemble with all the new gaskets, etc., asap, but put some ATF(maybe .5 quart) in with the oil.....this will draw out any moisture in the Bearings, etc. .....and trust me, that is the WORST place for water to hang out for anyyyyyy period of time. Lil rust rings in the holes?>>> no biggie, that'll get worn away pretty quickly by new rings......... Bearings? Not so forgiving.

Just my 2 cents, .... if I'm wrong, anyone, please point it out, ...but please..... no one pelt me with sharp shale pieces, k? lol.

Thanks guys. I will look into it. I drained it already but the local parts store is closed already. I will get out there in the morning and run some ATF through it with new oil and the new HG.

Hey buddy, ...

Just making sure I got this right.... You DO KNOW that you're facing a bad HG?????? Or you're 'THINKING' you might have one? Don't want you to tear something completely down for nothing, ya know? lol. When you pull the cover,...if it was steaming at all and kinda gutless.... You'll see some milk beginning to form on the rockers, chain, etc.

Far as the ATF, ... you just wanna run it 20 minutes with that, something like that, and then drain it.... so get one of those "5 Quarts and a filter for 17.99$, only SUNDAY, SUNDAY, SUNDAYYYYYYY!" thingymadoers! lol. Then replace the filter, Z, cuz it will be holding some of that water in there, ....don't want it making it's way back in there, ya know? Toyota has em for 4.30$ right now.... cheap as a Fram, actually.

Wish you the best, buddy... hoping it's NOT a HG, but sure sounds like it......

PS> Did you find the oil to be like Raw Unfiltered Honey? Not quite milk shake, but not CLEAR?

PSS> Check the coolant really well, too, ....see if you have any 'rainbows' or milk showing up in there, ya know? I didn't have ANY, ..it was strickly water pressure building up wherever the leak was, ...but nothing literally backing up into the H20 system, ya know?

PSSS> lol.... If you want that part number for the Fel-Pro Permatorque HG I used the second time... I'll gladly get it for ya... believe it was 26185PT......... All I know is, OEM failed me in 30 seconds, .... Fel-Pro did not, .........YET! lol. NOT EVEN saying OEM is lesser... but I've heard from my machinist, "People think they buy OEM, often, even at the dealer and that they're getting TOYOTA, NISSAN, whatever..... there is NO WAY, almost ever, any longer, that you can be sure ON SOME THINGS, not all... like HG"s for instance." What I DO know is that my buddy has used this Felpro HG MANY TIMES, when he's had problems..... and they've ALWAYS worked and almost always went 100K, without issue.

Again, ...just sharing what I'VE HEARD, .....I KNOW it's not Toyota-Bible Reference! lol.

Im not sure if its the HG or not. I think it might be though after talkin it over with my dad. It I didnt run it more than 5 minutes, didnt even drive it, and the oil did look like raw unfiltered honey. Thanks for the luck

I have always used the Fel Pro gaskets. The only other gasket I have used is the Rock gasket on the old mans 85. its almost complete metal and seemed to work pretty well. But we have used Fel Pro on everything that we have built, plus our machinist highly recommends them

.... yeah, ...well then, that sounds like it's around 90% or more surely the HG. When you pull the head, clean it like a BANSHEE with a scouring pad and warm VERY lightly soapy water, then alcohol on the HG surface of the head, as well as, well, what I did anyway; Cleaned out the rocker assembly REALLY well, including shot some PB through all the underneath of the rockers by moving everything back and forth, then poured ATF over it and worked it in, then dried it off by hand fairly well.

Do the same with the block cleaning, regarding the alcohol, after carefully removing ANY HG material that worked it's way into the block surface, ....then more alcohol with(what I used that left pretty much NO debris)..>>> a fine thread pilow case.

I also took a can of computer air and blew off all the milk from the chain and whatever I could reach with the tip(without letting that tip fall in there! lol... held on to it, haha)...then soaked it down both sides with ATF and across whatever I could reach on the timing cover/block surface, to pull any water lingering in there into the pan, then drained it all off.

Then, using more alcohol on Heavy Duty Cotton Swabs I pulled any moisture out of the head bolt cavities, till they were thoroughly dry again.... I was amazed how much water had drained into the Head bolt holes where there ARE oil passages, etc. ya know?

Ask your pops if you can carefully pour some ATF down the block oil passages between the cylinders, too(not the H20 ones, obviously, lol).... and let that cruise down into the bearings, while you're taking a bit of time cleaning everything up, drying it all with alcohol, ya know?

Again, just some thoughts, .... I'm sure pops will tell you whether some of what I'm saying is a waste of time....I just REFUSED to take any chances after having taken it apart/put together, 2 TIMES, in 3 days! lol.

Heres some progressive news. The head gasket did look blown from some tears in the gasket material. I got the timing cover back on along with the oil and water pumps. All I need to do is head gasket and put the head back on replace the fluids and give it a try.
