So my 90 GSX is at the mechanic because I threw a balance shaft rod, so I bought a new block since mine had a hole in it from throwing the balance shaft,so I sent my top end to a machine shop to get my head redone but when the mechanic cranked it up, it had no compression. He said he thinks this is because he forgot to compress the lifters before he cranked it, and that hes hoping everything will be all good once he takes out and compresses the lifters for a few hours. Then hes going to try and crank it again and thinks it will be right and done. Is this right? Im kinda flipping out cause I just want my car back and to be running right again. The thing that im worried about, is the person I got the bottom end from, this same issue happened with him. I got all the reciepts from the rebuild of the bottom end and my mechanic checked out the bottom end before we did anything with my head and he said it looked fine as well, so is maybe my block causing the issues with the lifters? Any help or ideas would be great thanks.
 
If the lifters have oil in them it may take sitting in the head overnight with spring pressure on them to seat the valves. It has happened to me on several ocasions when replacing head gaskets.

EDIT: This only applies after the valvetrain has been dissasembled so the lifters can fully extend.

That is exactly what my mechanic is doing, so that makes me feel alot better thanks. The mechanic said he forgot to compress the lifters before he put the head on to the new block.

As for saying I threw a balance shaft rod, that was my bad. I used the wrong wording. I threw a rod threw my block and there were balance shaft issues, but thats no longer an issue, because I bought a whole new block and reused my old head because it was still in good condition, but I sent it to the machine shop to get it hot tanked, surfaced new valves etc. I also did balance shaft elimination on the new block. Then the mechanic put my redone head onto the new block, but he forgot to compress the lifters before he put on the new head. Now hes got to take out the lifters and compress them before turning the car over again. What im worried about it, is are there possibly other things that would cause there to be no compression in this situation or is what im explaining feasable?
 
No problem. We all get confused sometimes :thumb: if it's not too late you can have the lifters empty in a couple minutes. No need to wait overnight. Just depress the valve inside and it will instantly release the excess oil.

Yep McGyver was right on all those TV shows. You can do anything with a paper clip.

I hope since he didn't compress the lifters he didn't turn it over without being in time. The valves could have hit the pistons when he bolted down the head if the cams were still in it.
 
i guess what im tring to say is that im not sure what is happening.What the mechanic said is that there is no compression so he had to take out all the lifters and pump them down.Those were his words exactly,thats why im confused.If he had the head at the machine shop and everyything was gone through,hot tanked and valves replaced im afraid that he might have bent some valves by what he did and i will have to get new valves again.He said right away that it was his mistake and that he would fix it but im just not sure what is going on.Would this make sense that i would have no compression if he just forgot to press the valves and if so would he have caused damage by doing so?Im not sure if he tried to crank it and thats how he knew there was no compression or if he knew somehow before that.Im just freaking out because im not sure what is going on.
 
thats why i try to learn how to do all my own work. you just cant trust anybody anymore when it comes to money

Holy crack nails Batman!

Anyway, back to the topic. If he effed something up make him pay for it.
 
Well he ended up pulling out the motor and there was no damage .It turns out that the head bolts i gave him were the wrong size along with the lifter issue.I have my old 6bolt head going on a 7 bolt built block so I guess he was supposed to use a different bolt size.I know that people are gonna flip me crap for using a 7bolt block,but he assured me that there would be less chance of crankwalk with stroker internals and some other precautions he took with a different.And i had got an amazing deal on this block.With all that aside he says my car will be done this evening and should run amazing.Basically i used my old head and had it hot tanked,machined,ported,all new valves and gaskets along with cosmetic head gasket and arp head studs.The block is seven bolt stroker bored .030 over that was gone over completely and done by a reputable machine shop in the seattle area.Originally i thought that it was bored .050 over but its not so thats a good thing.I just hope everything goes as he said it would.He was referred by a friend who had him build his 240 nissan turbo swap.And that car is a beast,although im pretty confident i'll be able to take him down with my gsx once i get it back.LOL Thanks guys,i'll let y'all know how this turns out tomorrow.
 
Sounds good. Give us an update when you get it back. I used to be an automotive machinist for Napa so I know what you're machinist is doing..The hydraulic lifter mishap is an easy mistake to make but fortunatly didn't end up a costly one. Between the wrong bolts and the valves not seating im sure this next trip will be the last
 
Thaks guys,i wish i would've done a 7bolt head as well but it wasnt in the budget.The machinist did a great porting job on my 6bolt head though.Now im just sitting here chewing my nails waiting for my car to be done tonight.I didnt get him the head bolts till late afternoon so he said it should be done by 8:00 tonight.Luckily he is willing to work late tonight to get it done,i think he kinda feels shitty for freaking me out with the incident last night.But as we all know,there could be other little minor issues to work out once he gets it fired up but hopefully nothing too drastic.
 
Well its been 2 days and my mechanic cant get it started.He hasnt given me much info on whats going on but i know it wont turn over.He said the timing is perfect and it is getting fuel and spark.The kinda sad thing is that i have just enough money to pay him fot the install and thats it.If i had a little more mechanical ability i would fix it myself,but i have sank so much into this car that ive lost all ambition to do anything else with it.Its been a fun ride but i'm going to get it towed to my house tomorrow and try to sell it as is.It has a fresh rebuild so someone with some dsm ability should score good on this one,especially with all the aftermarket parts on it.It has a new fmic with 60 miles on it,a perfect evo3 16g,walbro 255,beautiful new tb exhaust,nicely built shortblock ect etc etc.....So if anyone in the portland area is looking for a good deal let me know.I will consider trades as well.Thanks for the help y'all
 
No its neither,thats the first thing i said to my mechanic when he told me that he couldnt get it going.He has gone over EVERYTHING in the last 2 days and he is stumped.Im thinking it is something related to timing from when he tried to crank it the other day.Maybe a valve issue or something else that i cant afford to fix.I have put way too much into this car already,i dont really have the ambition for this car that i used to have.Ihave a pretty good grasp on mechanics but dsm's are another story.I respect them and the people who own them but i dont have the budget or the dsm knowledge to keep going with this car.Thanks y'all
 
Im sorry but that's not a good mechanic. His job was to rebuild your engine into a running condition. He made a mistake and he needs to fix it.

You should be able to turn over the engine with a 1/2" wrench on the front of the crank. Taking out the plugs will help. Once you see that the engine doesn't bind. Try spinning it with just the starter. If here is an electrical problem you can hotwire it by applying straight 12v to the smaller plug on the starter. On the 2g there's a connector by the bellhousing that goes straight to the small plug on the starter. Let us know what's the results. I'd hate to see a dsm sold because of a poor mechanic

I fully agree man.But there isnt alot i can do about it right now unfortanetly.I will go in and pay him for screwing up my nicely built block,because if not i wont get my car back.Then if i have the time to do it i could take him to court,but i cant prove alot since this deal was cash and it's my word against his.This was my fault,i should have done better homework on my mechanic or just did it myself.I hired him because he was recommended by a friend,and he was reasonable.For now i will just get what i can out of the car,which wont be shit in it's mechanical conition,and save up for something else.You live you learn yo,ill chalk it up to that.

Well now he is saying that it might have to do with the distributor.He said something about having to spin it 180 degrees or some shit,i think he hooked it up wrong or something.I got the message from him on my voicemail and it was hard to understand.I've never jacked around with my distributor on my gsx so i dont know if that could be possible,it doesnt make sense to me.Also he is going to get some new plugs since the old ones were fuel fowled for some reason.Maybe he will get lucky and get it going this time i dont know,honestly im getting to the point where i dont care.That car is my baby and it is going to crush me to get rid of it but i have no choice.I just hope i will be able to sell it as a running car.Someone should be able to turn this car into a total bad ass pretty easily if they have enough dsm knowledge.It was dynoed at 311 awhp before this happened so im sure its capable of alot more with the stroker internals,ported head,bored block,balance shaft elimination,a new lightweight flywheel and all the shit that i did to it before.Ill see what happens today,if he cant get it started by this evening im sending my tow truck guy over to his shop to pick it up.Then it will be on this site immediately and craigslist for sale for best offer.The body on my 1g is amazing as well,i have only seen a few panda's as clean as mine so it should go fast.Thank guys

Well i got it going and the motor has rod knock!! After all that ive gone through with this car and all ive spent.i got screwed by the guy i bought the block from or my mechanic,who knows.The mechanic said he could drop the pan and send the rod to get sized and the crank to get machined.He thinks that would take care of it but i dont know if i trust that.The last thing i want to do is spend even more money for nothing.Thanks for everything though y'all,im out yo!!
