comp. test incorrect?

[93s13]

if you do a compression test on a ca without hooking up the vaccume lines or installing the turbo, what would happen? i sold a motor to someone more than a month ago and hes calling me now wanting his money back because the compression is low, but when i sold him the motor i just took it out of my car and it ran fine! he told me he did the compression test without the vaccume lines hooked up or without having the turbo hooked up.

shouldnt matter just get it to normal operating temp. after that remove all spark plugs and while cranking go Wide Open Throttle.

well than wat could have possibly went wrong from me to him?

What was the compression #s? If any one cylinder has greater than a 15% difference, he should be worried. If you did a compression test and things were inline and you are being totally honest, then the only other question would be, did they install it and drive. There's no way the compression changed between shipping and installation.

The ancillary's being hooked up shouldn't matter.

When you did the compression test, was the motor warmed up or cold? When the guy did the test, was the motor warmed up or cold?

When you did the test, did you remove all of the plugs all at once and did he do the same?

When you did the test, do you hold the throttle wide open and did he do the same?

Do you see what I'm getting at? I suspect that he didn't perform the test properly, hence the low #'s. As Dee said, the BIGGEST thing that is important on a compression test is VARIENCE between cylnders.

yea i thought he did something wrong also, he said he would need a month to install it and it was 2 months before i herd from him. out of the blue he calls and says he did a comp test and the #s were bad he wants his money back. but i wasnt there for the install or the test nor do i know if he got it running and f'ed it up somehow. so i dont know how to go about this. do i give him his money back and get stuck with a posibly f'ed up motor or what do i do? i know it was nothing on my part, the comp test my friend did was fine. motor ran strong for a while. now hes having problems and there is no explaination for it, his friend even said he doesnt know why its happening.

Direct him to this forum.

thats why i started this thread, i have also tried telling him to come to this forum, but i dont know i guess he didnt otherwise he probably wouldnt have the problem he does. i know its not me because the motor ran fine and strong when i had it. he admitted it was if first time playing with the CA and when i gave him the motor the head had to be put back together. he also openly admitted that he didnt know **** about the vaccume lines and he would need my help, which he never called for. i just have a really bad feeling that he killed the motor and obviously doesnt want it now and wants his money back so i am the loser in the situation.

Well, people need to know what they're buying, hence I tell people when they get a motor set, just drive the thing right away because if they chose to start doing all the maintenance stuff, warranty is voided. After 30 days, warranty is voided and if you said two months later he's crying for his cash back, I'm sorry dude, I would tell him your window of opportunity is closed.

Unless I can personally verify that you did not install the motor till a later date, after 30 days, you're on your own. So now he needs to either repair his engine or buy another one, I'm pretty sure he bought it cheap, so in cheap, this is usually what you reap. Hate to be harsh, but some of these kids needs to understand the importance of business. You wreck it, you bought it. And if no warranty was expressed or implied, normally, the standard warranty for this business supercedes all other for the first 30 days which basically says you need to install said motor, drive it and you have 30 days to call me and tell you're having issues. And these issues does not cover overheating, melted pistons, blown headgaskets because of melted pistons due to overboosting, foreign objects in combustion chambers, etc. It only covers the bottom end and the head. Turbos are wear items and cannot be warranted. Hope this helps shed some light on your dilemma.

oh it deffinatly does, and he did get it for an amazing price, i mean fmic, greddy oil lines, power xs exhaust mani, 3 inch d/p 3 wiring harness's and a **** load of other parts for 1,200. plus the motor only had 60,xxx miles on it. ran like a champ when i had it. i mean we did have a contract to hold the check he gave me for 1 month which i did than i cashed it. and now he wants his money back. i will talk to him more and find out EXACTLY how he did the comp test. and explain to him the motor is his i will find him a new KA being the only thing that feels right. i mean he still got a steal for a project motor and thats all there is to it i guess.

[float_6969]

I'm with you on this 93s13. I think you gave the guy a great deal on a low mileage motoset with options and even held his check for 30days. I would tell him that you're sorry and that if he want's to persue it further, it'll have to go to court.

[Chris859]

I completely agree, While it does suck that he is having problems - I don't see how it is even remotely your fault. I am more than willing to bet he messed something up, and wants his money back simply so he doesnt have to eat the cost. If he put the head together as you said, maybe he had the cam timing off and bent some valves - it only takes one time. If you get your stuff back, and refund money, I would only give a partial refund. Lol, maybe ill buy some of the returned parts off of you

[93s13]

lol...thank you for the support guys. its actually helping me prove that i am in the right on this one. he did send me a long email explaing how wrong i was in even aspect and trying to pin the motor going bad on me. but heres something i just thought about. he left me a voice mail last week that the motor was "bad". when i called him back to confront him, insted of telling me the problem, he kept asking when his turbo was comming in. I had to be the one to bring up the message. why i dont know. but here is how he ran the test....

"I ran the test by bolting everything up, liining up timing and then bolting the trans and starter to the motor. You dont need spark or fuel to run a compression test so what i did was i cranked the motor with a spare battery that i ran wires to the starter....."

than he continued to cry that i didnt sell him my oil cooler because it wasnt part of the sale. well i told him i will give him the link to this thread if he wants, and i did offer a partial refund but told him thats the best hes getting. so i will keep you guys posted. if anything and i get the motor back, i will recheck what he did wrong, fix it and resell it once its in tip top condition. i just hate people who break **** and try to pin it off on the seller. my loss was his gain and he ruined it and now i guess its my fault?

[93s13]

P.S BOOSTBOY: he didnt give me the compression numbers which makes it that much more fishy. he actually refused to tell me until now how he ran the test.
