Motor is gone

Probably couldn't do a worse job than Larry H..... Doh!

Haha, true.

Definitely sounds like you are off a tooth. Glad you are getting this beast figured out. Hell, you should be a modular expert after all this! LOL

Sorry Ron . Just for my info , if 1 bank is a tooth off either direction then that side will have alot lower comp. than the other. Correct ?

I would assume so

 

[05stroker]

I would assume so

Reason I asked was becouse of the big psi gain I had after the last build and the hp stayed the same with more psi and the same timming as before and the two banks are very different on the dual WB on the dyno. Bank 1 is leaner then bank 2 on the dyno. Something to ck out this weekend. I was going to pull the front cover and inspect the timming gears and all is why I asked.

Ron I just played catchup on this thread. Sorry to hear Larry is an asshole and you're having problems. Makes me happy that I stopped working on and racing my car once I hit a 12.7. Right now it's just a 80k mile daily driver. I'm having more fun confusing the shit out of people with my hybrid emblem and offroad H/slp loudmouth combo. When people ask me if it's a real hybrid, I say it's alternative fuel. Runs on a concentrated form of the active ingredient in BULLSHIT. Hang in there, sounds like you're getting this figured out.

Well its not the timing of the motor. its timed properly it would seem. I still dont understand anything about timing but by looknig at it my dad is convinced it is timed ok.

I am on the verge of parting it out

 

[ZmanM3]

Wow, that sucks!

 

[nycmikie1]

Parting it out now RON?????? not the answer you will lose to much money and all your time THINK RON I know your tired and burnt out from all this abuse but don't give up now the leak down was good so try moving the chain on the bad bank and do a compression test anyway think of it this way the top end needs to come apart so try things to avoid pulling the heads and being I have not done any mod motors can you switch the cams or maybe you have a stock cam to put on that weak bank to get a compression test to see if you get 150

[94tbird]

I dont know mike. I jsut dont know. Theres no reason to move the cam or chains as they are timed properly. Only 1 lobe of the cam was damaged so that cant cause 4 cylinders to have less compression than the other 4. The entire motor needs to be rebuilt from the ground up. Obviously I do not have the experience or the money to do this. Parting out will lose money for sure, but will nbet me more than if i tried to sell the car in its current state. Well see what happens in the next few days

 

[ZmanM3]

I really want to know why it is off on the compression like that.

 

[94tbird]

welcome to the club

 

[ZmanM3]

I feel you. Instead of parting it out though you could just drop a stock long block in it and turn down the boost to livable levels for a while till you can afford the rebuild of that engine.

 

[94tbird]

stock motors cost money too matt. and that would be a min of 1500-2000 if im lucky in the wrong direction

 

[nycmikie1]

I was not thinking about that 1 bad lobe I was thinking the cam timing built into that 1 cam is off from the factory Ron go for that cam switch it with the other if that can be done or switch it out with a stock one and do a compression test if it makes you feel better we all have this crazy shit luck with cars I always have to work very hard to get my way and talk about shit luck when I sold my pro street car to the new owner and now a good friend I built a 598 what I believed would be able to drive around on the street and spray it so a 3400 pound car can click off a 7 second pass and it did RON 7.86 173mph but we are always taking out pistons after a few runs so after 3 sets of pistons the new owner had changed and all different tune-ups for this 400 shot we are still chasing the correct tune and this is a show car so it makes the job really suck to do so the reason for this boring story your not alone go after those cams!

the cams arent interchangable as one is longer than the other. they are side specific due to the chain guides and tensioners and such. I would need a new set of cams. Stock cams would work but i dont have those either

 

[nycmikie1]

I am sure somebody here would lend you a stock set to try listen that leak down is telling us your Pistons and ring seal is fine your valves and valve job is fine and head gasket is fine so it can only be that CAM or the Chamber size C.C IS way off from 1 head to the other or a thicker head gasket on 1 side of the engine or somebody machined the deck more on 1 side of the block IF it was me I would be going with that cam swap!!!!! Its just your time Ron drink some beers with friends in your garage and do it.

That's what I was about to say. Beat me to it! Don't part out the car, if nothing else you can't let it beat you mine was down for a year, it sucked, was exhausting mentally and financially, and fought us every step of the way, but in the end the first drive she ran right was worth every last drop.

Ron
My Shit Box and they all are !!!! I was bored from drag racing and went a different way and that was buying this Mustang Every single thing I did with this car from brand new has been a real task and double money we are all looking for the perfect combo on these cars but I will tell you this never think that those cams can not be degree in wrong when built the difference is when you check it on lets say a chevy engine they sell lower gears the move +2 +4 +6 and -2 -4 -6 to correct that there is not a lot of things that can do that other then what I posted above and to ad to that list 4 different piston on 1 side of the engine then the other side the main thing is that leak down is good go for that cam swap you know you will not be happy till you find it anyway!!!!

 

[nycmikie1]

What about those cam lock outs??????
Put that back to stock and do a compression test !!
That will change cam timing.
