Would a bent valve throw that u1424 code with the p0300?
This is shot in dark but how many times did you pull heads? How many times did you reuse head gaskets?
I have not reused a single head gasket. I thought about it, but Oreillys had one in stock and I followed y'all's advice on not risking it.
100% confident on timing. When I went back into her to verify timing, I removed oil pump and aligned marks per instructions. Verified timing marks before putting timing cover back on. I replaced the injector that corresponded to the port that was filled with gas.
Change out that thermostat. And sounds like a clog somewhere. Sounds like thermostat never opens. Sometimes those t stats bad out the box.
New one went in same way old one was. I will double check belt. Prolly get new tstat tomorrow.
either that or air locked not known a ram to do it but have had others do it run it to operation temp with rad cap off see if it starts blowing it out if it does let it cool off then fill it again may have to do this a time or two. like I said I have not had a ram to do this but my truck is the only gen 4 ram I have worked on lately
Also you may know this but just in case this would cause your issue. Always fill a radiator first with engine cold then with cap still off start engine you will now be able add more coolant but wait do not cap it off yet you still have the block to fill let it get to operating temp just before t-stat opens sometime you will start to loose a little coolant out radiator cap but still wait once t-stat opens the coolant will pretty much disappear now you can fill it some more. It's not going to hurt anything at this point let it continue to run that will keep working air out you will more than likely have to add a couple more times once it can sit and run for 5min or so and not drop level now you may cap it off and check for pressure leaks.
Tstat could be bad even if new. Also these are a pain in the ass to burp the system sometimes not uncommon to overheat a little after first time adding coolant. Let it run rad cap off I have a funnel that fits inside the rad cap they sell them pre cheap just shut it off let it cool down repeat ect get that air out.
