TRON Posted December 12, 2014 Author Report Share Posted December 12, 2014 if youre spending 3k might as well get it rebuilt.. i would never run a used engine. you never know how others treated the car and how often they changed the oil (if they did) no matter how good of a mechanic he is he cant just pick a good engine.. chances are its just bs too. can be the head gasket or the seals on the heads that's making it leak oil. i have heard that story many times.. like oh you blew your intake gasket and your intake is broken. it will cost you $800 to repair it. all i had them do is change the spark plug and for water in the cylinder well take a wild guess. its been 3 years and i havent gotten water in my cylinder... all mechanics are dirty no matter how good they are and how much they say they are youre friend. seen it happen many times.. if you didnt watch him remove the spark plug then chances are he got it wet while you wasnt looking. I agree its all a crap shoot no matter what you buy, but this mechanic isn't trying to rip me off. He's a long time family friends and been servicing our vehicles longer than I've been alive. It would be different if it was a GM dealership and I didn't personally know the mechanic. If your truck isnt dead yet, Just run it to the ground, Then do something. It is pretty much dead. Had to flatbed it into the shop because it wont even idle.

Miguels Posted December 12, 2014 Report Share Posted December 12, 2014 It is pretty much dead. Had to flatbed it into the shop because it wont even idle. If your truck isnt dead yet, Just run it to the ground, Then do something. same thing is happening to my coworker 2002 escalade.. it was running fine and just a few days ago it just started to back fire. like it was good when he turned it off next day it wont even idle and pops. it might be the same thing and could be the plug wire, plugs, or coil as for oil on the plug. just change the plug and check it yourself after a few days if driving.. i wouldnt trust a mechanic even if he has been doing my rides all my life.. dont forget he has a family too feed and a roof to provide and doing $50 jobs wont cut it.. when it comes to money you really cant trust anyone edit: my brother was the same way. trusted a mechanic. he was leaking water in the oil his machanic said it was the intake gasket. fixed it for $500. few days later there is water in the oil again.. well now he had to pay to get that gasket replaced and get a new head gasket.if my brother would have listened to me he would have only paid $500 but instead paid $1200 and secured that mechanic 2 weeks of work. i told him do your head gasket. you will get free labor on the intake gasket since he has to take it off anyway.. he paid labor twice for the same thing my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
TRON Posted December 12, 2014 Author Report Share Posted December 12, 2014 It's not a cylinder misfire or backfire, it has no compression. It sounds to me like a bad valve problem. The other cylinder being coated in oil could be bad rings or a crack in the header which would leak oil into the top of the cylinder. He checked all of the electrical and it's working fine. I get that you cant be %100 sure about anything, but I don't really have a choice. I don't have the experience, knowledge or resources to diagnose the problem myself so I have to trust the mechanic.

Miguels Posted December 12, 2014 Report Share Posted December 12, 2014 if you have broken seals it can cause the same thing. you might not even need an engine. broken seals happen more often. then ring failure. seen many engines lose compression because of the seals. headers wont leak oil since oil dont go through them. its just air.. my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
TRON Posted December 12, 2014 Author Report Share Posted December 12, 2014 I'll find out more tomorrow and I'll definitely ask about any other solutions than swapping, but if it's going to cost me a lot of labor just to pull the engine apart only to find that it does need to be replaced then I've just wasted money. It's all up in the air right now.

Broke_Audio_Addict Posted December 12, 2014 Report Share Posted December 12, 2014 Since you're considering the swap have you considered swapping to the 6.0?No. I don't want to make thing anymore complicated for the mechanic. I need this fixed asap because I can't be borrowing my gf's car for much longer. the votec 6 is garbage and makes garbage power with garbage economy.Yep its such a piece of garbage that lots of guys trust as their planes engine. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

Miguels Posted December 12, 2014 Report Share Posted December 12, 2014 if whenever my 454 breaks down im getting me a 6.0. its a nice piece of junk. fuel economy? i bet it will do better then my 454 my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...

Ahmed Johnson Posted December 12, 2014 Report Share Posted December 12, 2014 I would get it rebuilt. Even a one year warranty on a used engine is a risk. At least rebuilt you won't deal with others problems. Link to comment Share on other sites More sharing options...
Marquisboys Posted December 12, 2014 Report Share Posted December 12, 2014 Kind of a toss up, rebuilt takes longer and once he digs into the engine wasting time he could find the block is cracked and cannot be used. Also he could find things wrong with the engine resulting in more money than just buying another engine. Another engine could have less miles but not sure how the other person took care of it. Days or weeks down the road shit could go wrong with the used engine resulting in more money and time wasted. 2004 Grand MarquisAA Mayhem 18Crescendo 3500d6.5's AQ Pro AudioAQ Super TweetsImage Dynamics 6x9Soundqubed 125.4MB Quart 80.4144.2 db GONZO 2013 Chrysler 300S Granite Crystal Metallic Exterior Inferno Red Interior 5.7 HEMI AWD LMI Air Hammer Intake Corsa exhaust Custom Tune Link to comment Share on other sites More sharing options...
