I admire you for doing all this work but I really don't think this is going to be an engine that lasts very long.

1)
Sand blasting pistons? Bad idea.
If you are going to the trouble to take the pistons out, and clean them up, if you take off too much material they become out of spec. I don't see you using a dial gauge to check your bore or

2) plastigague is great. only for checking spec in one area of your mains. It does not check out of round. half an inch over, your crank could be too tight, and cause issues.
I personally found this out the hard way when I purchased a dial gauge, and found out that I was 'out of round'. This required a 'line hone' from the machine shop, different berrings and a micro polish to get them to seat properly.

3) what do you have your ring gap set as?

4) I understand you purchased stuff from the machine shop, but are you positive its all going to be within spec? What is your rod ID vs your Crank OD?

These are some things to take into consideration before you go building your engine. If I would have let the machine shop assemble my bottom end the first time I could have saved several hundred dollars. Doing it right is sometimes letting the professionals do before you find out the hard way. So far in your pictures, I don't see you checking any of the important things.

Well the machine shop i went to said my crank was still good and that my bore, pistons, bearings and ect was standard. I asked what bearings and rings would fit and he said to get standard sized bearings and rings..
most of the engine is already put together. This is a daily drive application so i think it'll be alright. I'm not looking for crazy horse power anymore. Probably when i get older, more experience, and have more money, I'll get something fast.
If anything bad happens, I'll take the consequence.
ahaha wish me luck! Thanks for letting me know

Walperstyle · 04-27-2012, 02:26 AM

All that trouble, and you still don't mind half-assing it and trusting the machine shop. ...I still don't like the idea of sandblasting pistons though. Not my thing.

I'm currently helping Bruce with this project. We got everything put back together and we find that the head gasket is leaking coolant out on the wall of the head/block. This is because head gaskets are a one time use thing and we mounted the head and took it off twice because 1) He forgot to use assembly lube on the bearings and 2) The head studs he ordered were not the right ones. We are currently taking off the head and all the necessary parts to throw on a new head gasket and hopefully all will go well.

xh3nry · 05-22-2012, 01:07 AM

We did not start the car, coolant was leaking as it was going in.

xh3nry · 05-22-2012, 08:55 PM

Video of start up:

Video of test drive:
http://s165.photobucket.com/albums/u...t=M4H01180.mp4

Started overheating after the test drive, either one of the hoses are damaged or the hose is not connected tight. Also has a vacuum leak i'm assuming because the car stalled after a 4000 rpm drive.

xh3nry · 05-22-2012, 08:57 PM

New head gasket btw!

brucetrann · 05-23-2012, 01:49 PM

woooo its running !

xh3nry · 05-23-2012, 06:18 PM

Need help: The car turns off after being turned on for a minute. Volts of battery drops to 8.9 or 11.5. Thought maybe it's a bad alternator but we just got it checked out and it's good. Battery is 2 months old. What could it be??

Driftwire · 06-07-2012, 07:52 AM
