Seat belts save lives. The cuts on her head came from when she unbuckled herself and fell on the ceiling of the car. I don't want to even think if my son was there.

 

Is there a way to replace this seal and those gears you're talking about without tearing into the sc?

 

Hi guys, so this thread has been known to be my blog so to speak. It's been a long time since I have posted here. I have some bad news, I did not make it to 300k mile marker. I'm just shy of 290k and lost almost all compression in cylinder 4. So I pulled the head and found too many cracks to count. Some going half way up the spark plug threads, some over to the water jackets, most going under the valve seats. The head is garbage without saying. My valves, springs, retainers are all in perfect shape. The valves had less than a thousandth of wear on them so I may sell them to recoup some cost down the road. I have found a solid rebuilt head for 750$ I think I'll be buying. It's complete with rocker assembly and cam. Which I won't have a need for(I'll move my rockers and cam over). Here are some pictures of my busted head.
Looks like all my cylinders were being steam cleaned. My compression test was 125/120/130/60 psi. The photo of the valve seats was at cylinder 4. My bottom end seems fine. I just had the pan off and replaced my timing assembly and oil pan gasket as well as oil pump, I put a new belt on too. My boost went from 14 psi to 18psi where it should be given my mods. Then the head went. I'm guessing I had these cracks for a while and must have had my timing off a tooth or two and when I redid my timing I gained back my power which pushed the limits of the already weakened head causing it to finally crack all the way through. I had combustion gases coming out of my oil filler cap when I was compression testing cylinder 4 as well as air bubbles popping up in my coolant reservoir. The others I didn't have combustion gas emitting from the oil filler cap but I never took the water reservoir cap off until cylinder 4. So I'm thinking I probably would have had the same bubbling in the coolant from the others as well.

Also the coating on my supercharger turbines is coming off. Is this something that should be addressed immediately or wait until it fails?

I spoke to Jan from rmw and to Mike at thumper heads. Both heads are 2200-2600$ and if I know I'd be happy with either head. But if I snag this stock rebuilt head for 700 then that leaves money for the alta light bar bracket, an oil cooler, a cheap header like Megan and a wideband gauge. Plus I'll probably run a oil catch can. Not to mention the gaskets and head bolts will run me another 120 or so. So there's a huge variation in costs. My cars fun for now anyways. If I go with a BV ported head I'd want it tuned and I'd have to worry about leaning out with my stock injectors and my oem header would be a huge restriction. I also plan to have my CSF radiator repaired and reinstalled once again. It blew probably from my combustion gases over pressurizing the cooling system..

While the functionality is nice I plan to keep mine all level with each other and looks like I'd have to buy two of those kits to mount my 4 hella 500s

Today I dropped off my CSF radiator. If its going to cost me too much to repair it then I'll probably just end up buying another. Not really sure why but they said they made need to remove the entire tank if the crack is from the core to the tank. And upwards of 175$. That's just ridiculous. I said call me before you do anything to it. Has anyone had any luck JB welding aluminum radiators? If the cracks on the horizontal part where it mates with the side tank couldn't I just pull back some fins and JB weld inside of it and use a tooth pick to spread it around? It's gotta be pin hole sized because it wouldn't leak without the coolant at operating temps. And it would just hiss as it barely came out.
