Well last week my fuel rail mount broke off the manifold.. its not actually the mount, its the screw in point on the manifold that broke.. it was tighten too much last time it was done. Anyway so I ordered an early 2000 manifold to replace mine with. Sucks to be paying for the whole piece just for that stupid cheap plastic screw in thingy but anyway. Was kind of a bitch to undo all the wires but its nice that all the connectors are different.. so you can't go wrong when replugging them. i couldn't reach the stud/bolt where the alternator is in front. I finally managed to get up and get everything off and ready to put the new one in.. was happy to find out the manifold i got in the mail, still had the throttle body on it, sensor in the back, egr still connected.. i think its from an automatic though..
I installed everything back on, started the car up and it had a bit of trouble stumbling at first but i had disconnected the fuel rail so i thought it was repressurizing or so.. but then the engine kept going up to like 6000rpm and then fall back and stall.. so i looked at the connectors, one was plugged just not "clicked".. still the same.. went up high in rpm and then stalls. So i checked vaccum lines etc.. the pcv was disconnected :rolleyes: so i had a huge leak in there.. reconnected it.. and then the car started fine.. i let idle for like 15 minutes. It hadn't ran for over a week, then i went for a ride. Car stumbled a bit when i floored it so i let off.. then after 5 minutes or so it was fine.
So i was just driving along for maybe another 10 minutes and started hearing a weird sound.. like spooling but alot louder.. at first i thought the turbo blew or something. So i stopped, looked under the hood.. smelled like exhaust.. the car was still pulling and everything and making boost. I then went to a buddies house and showed him and we found that it was my exhaust manifold flange and adapter plate that was leaking. There's no gasket (stock cat. doesn't have one either but theres like a "bevel" beed or whatever to form a seal. Anyway so i drove back home to park it and it was worse.. car was barely making boost (its leaking before the turbo) so it made sense.
Now what do i need to do.. could it be the turbo exhaust inlet that's been warped? or manifold.. or just the adapter plate between the two. I was going to buy some Permatex Copper High Temp silicone gasket maker and put it between the two connections. You guys think it'll hold? should i have real gaskets in there? it would need to be custom has there aren't any for the exh. manifold (there are for the t25 flange) Anyone tried it before for exhast leaks? I put some high temp red silicone from permatex but theres no copper.. and it holds up to 650*F (while the copper supports up to 700*F).. I let it dry over night so i haven't tried it again..
any ideas anyone? kinda pisses me off that it only took about 10 minutes to break again.. i dont understand why i did either.. its been running fine for the last 2-3 months.. oh and i tried retightening the bolts but it didn't do anything.. so there's probably something that's not "flat"..
thanks guys
