What should I do....

[Deevious]

Ok heres the deal, I currently have my supra up on jack stands since the day I took it off the hands of its previous owner and im running out of storage space for this car since its not running....basicly the short story is I drove it home, and took it on a couple of drives around the block when it developed a overheating & Tapping/knocking sound that I still can't figure if its rodknock or just something loose in the engine, it basicly sounds like taking a quarter and tapping it on a wooden surface rapidly and it only starts at about 1,500rpm and skips a bit a little after.

After that I spent about a week f**king with stuff trying to figure out what was going on even though I knew in the back of my head it was time for a New Headgasket and possibly bearings. Anyways im kind of short on funds and I dont wanna go tearing into the bottom-end until I can save up the funds to get exactly how I want it built(Forged), so my question is should I just get a MHG kit with all the other gaskets & ARP headstuds until I can build up the bottom-end?

Also if your wondering I'll be going the HG work myself, im pretty new to Supras(my first one) but I've owned 3 modded mustangs that I worked on myself so im pretty confident when it comes to these things.


Note - Im NOT sure if I have rod knock, a shop told me it has low compression in 2 cyls(headgasket prob), and the noise was probably valvetrain....



Thanks

Are you sure you've got a BHG? I don't think that a metal headgasket is a cure all. Make sure you know what the problem is before you try and fix it. If you're low on funds, you don't want to spend money on something that isn't broken. Good luck and keep us posted.

sure sounds like rod knock... I'd check and make sure you've got that (whatever it is) fixed before you put a headgasket in, cuz at this point it may be about as useful as putting lipstick on a corpse.

Yea I think im just gonna bite the bullet and pull the motor, I've read a could of thread that even replacing just the bearings isnt good enough but on the positive side...I'll learn a little about the 7M just wish I could get it running soon been anctious to drive this thing since the day I bought it hah.


Anyways thanks for the help and knocking a little sense into me before I went out and did something crazy. There will def be more postings from me once I start tearing into the motor :momaru: haha

your laughing now. imo, best route 1jz, swap, splice, call it a day. esspecially if your having to bite a bullet to pull the engine out, just thinking about the box of bolts for the head alone makes me cringe.

I thought about that but I prefer the torque the 7m provides low in the powerband. As far as the PITA factor I should be ok if I keep everything organized and labeled..... i just gotta actually get off my ass and start tackling it.
