BAD NEWS The Insane Stang is dead

well i got everything running and running good...the oil pressure was perfect and then after it go warmed up all hell broke lose AGAIN the oil pressure was droping....i have replaced to oil pump the oil pump shaf, cleaned the pick up tube, cleaned the oil pan. and added the some good oil and changed the filter...THAT did not fix the problem...so i have come to find out that the last thing and the worst thing that it could be is the bearings are toast..how this happened i have no idea... but i will be posting all my stuff very soon... i am going carb and with a R block...planning on a carbed supercharged 331....:bawl: :bawl: :bawl:

[Traceman]

So does that mean you are going to pay up on the dyno bet now since you are not going to make 350rwhp with that combo?

:angel:

for the last time the bet was if i made the numbers on the dyno not if i could not make it to the dyno......i will place bets after i am done with my new engine...but this time i am saying the hell with the dyno numbers...i will just race for the money..so that way it will be fare....and plus i can not say my car is down and not running:angel: ...but i might say i spun off the line...j/k...:angel:


i have been checking DSS and Coast High Performance which one would be the best,,,,,,,

i still don't understand what you are having a problem with. low oil pressure? no oil pressure? it is not that uncommon for the oil to heat up and the pressure to drop. does the motor make any unsusal noises? hell, if it seems fine , run it . if it breaks,rebuild it.as long as you have perssure at idle and the pressure increases with engine rpm and load you should be fine.

ok when it started to drop.....at idel it ran about 5psi on the auto meter oil pressure....so i rev it up to 3,000 rpm on the stock tach and the oil pressure was at 20psi........now when it was cold it ran about 20psi to 40psi

[gt350mustang]

did you bleed the air out of the oil pressure line? what happens when you drive it and get the rpm's up around 4,000 to 5,000 under load? is it still at 20 psi?

[HoustonLX]

Why go carb'ed and supercharged? Thats not a very common set-up. Not that it has not been done, but you will have a much more driver friendly car if you stayed EFI and supercharged. You have a combo that will make great HP just by adding a supercharger now and changing the fuel system a little. If the bearings are bad and the rest of the motor is good, why not just pull the motor and replace the bearings? That will save you alot of cash. Plus it will be a good starting point for the SC you plan on adding. You are still learning how to work on the motor you have now. You already want to go with a more radical combo? Hell, you can't get this one to run!

[HoustonLX]

Tim, I have an idea. You keep throughing away money changing combo's more often then most people change underwear. Why not just give me the cash and we will call it even???

Seriously though, you have bought more parts and cars in the last year then most people go through in 5 years. Stop changing combo's every time you run into a little problem with the car/motor you have now. If you continue doing that, you will NEVER have a car that runs for more then one week. All modded cars have their problems. Learning how to work on them is part of the learning curve. If you change your combo AGAIN, you will lose more money. Again, just give it to me instead of throughing more cash away. Hell, I could have built two quick cars and had them running good with the money you have wasted.

I thought his mega monster motor was going to be built by some expert Ford guy? That's why you were dulling out so much shit about it. If the bearings are shot already doesn't say much about who built the motor.

well after a hr of cooling it went back good again....i am guessing it is suppose to idel at 10psi per 1k rpm????....this is making me pissed....when it get heated up it starts again.... when i firsted again I rev it up to 3k rpm it read 30psi is that where it should be???...i just want this damn thing to run right...

he has not looked at it yet but from what i told him you says it might be the bearings

Huh? Someone decipher that please.:confused:

[Timebomb]

So what exactly is the motor doing? Are the rods knocking? Can you hear anything abnormal when it gets warm? When you had the pan off did you check the rods for exces play? When you had problems with it before did you ever run it with low oil pressure or no oil at all? Give us some more information...my truck had great oil pressure on start up and the then it would fall to next to nothing when it warmed up and you could hear the rods knocking. When I pulled it apart, sure enough the bearings are toast and the crank had some nice wear on it.

Look at it this way...if the bearings are toast your only looking at $65 to have the crank turned and about $45 in bearings and your back up and running...Thats a lot better than a $4K shortblock! I know I'm not made of money....maybe you are!

well i have not noticed any kind of knock yet....i have never ran it with out oil

[Timebomb]

I'll ask one more time...what exactly is the motor doing? People have already told you what to check out, if its not making any noise and has oil pressure that increases with RPM what makes you think something is wrong?

No offense, but replying to your posts asking for the same information when we are trying to help gets real old, real fast.

well it idels at 5psi when hot....when it was ideling at 40psi.....and when i drove it on the street and i down shifted to 2nd and got on it and let off the engine killed for what reason i have no idea.....and someone told me that the oil pressure is suppose to be 10psi per 1k rpm...and would this knock be loud??????

[Timebomb]

You'd be able to hear it if the rods where knocking. Your motor dieing after you let off is just in the tune and porbably not oil pressure related. What is your oil pressure at WOT?

ok when it was cold it would zip up with the rpms...but when hot it is real slugish..not real sure on what it is on wot....last time i think it was like 75psi

[89 coupe]

Tim if you only have 5psi at idle hot you have a problem. It might not be knocking now but it will be shortly if you keep running it.
It sounds like the bearing clearances were never checked.
In other words it was not built right. It is most likely crank bearing clearances but it could also be cam bearings, oil galley plug leaking, wrong lifters, and who knows what else.
Don't take this wrong Tim but from reading many of your previous posts, you should not be doing this yourself. I would recommend finding a good engine machine shop.. Take them your long block and let them go through it, pay the money and you should be ok. For a standard rebuild you won't be out a lot.

[Timebomb]

LOL, whats slugish...the car or the oil pressure? Sounds like you need to tune your car and the oil pressure is may or may not be the problem.

maybe you are right.....i hope that is the case but i am going to get someone to look at it and tune to make sure...GOD let me pray that is all it is......i pray to you mustang god :hail:

cause when i had the guy i know tune it , it worked fine and was running very good...we where reving it up and it set at idel for 1.5 hrs or more and everything was fine.....i messed up the tune a little...could me messing it up really casue it to have messed up oil pressure

No, the oil pump is driven by engine RPM's. It really doesn't matter if the motor is running good or not, you should still have more than 5 PSI at idle. It is possible the motor might last a while like that if you are seeing 30 to 40 at higher RPM's, but something is not right.

o well i think i will try the easy way first and listen for one time in my life...lol.....rebuild prices anyone....and i was told by fred that there is a machine shop in tomball anyone know the name or number.....and my block is not 0 decked like i thought it was like 30ths-25ths away and the block has been sleeved....should i get a new block or what..is the sleeviing ok?????

ok when i got the car it ran fine nothting wrong.....then the oil pump shaft came out and got stuck in the crank while i was turning it with a wrench to 1 cyl....so i took the oil pump off and reset the oil pump shaft and that is when all this stuff started to happen....i even replaced the oil pump a few days ago and then it happened again....i was told since i did not tigthen it down to spec this could be a very big problemm....cause i don't get it when i took the oil pump back on all this shit starts to happen...and everytime i have broken the engine down i have always primed it...and i have spent damn ner 100.00 just in oil

Westside machine has a pretty good reputation. I believe they are located on Emmott street. Don't have the phone no. with me. A sleeve is usually ok if it was done right. You can take your motor to them and for a small price they will take it apart, check it all out, tell you what you need and how much it will cost. Tell them all you know about the block and what your oil pressure is doing so they will be looking for possible problem's that might get missed.

[Rusman]

Westside is 9100 Emnora, 77080. It's about 5 minutes from my house and about 30-45 minutes from Tomball. They are good guys and it's worth the trip, if you ask me.

Hey Martin thats our bodyshop that is located on Emmot St. lol:razz:

Emmott-Emnora They all sound the same to me. I know how to drive there. Bet I can find both places Brad, but I wouldn't go to our body shop for any work:p
