IMG_8937.JPGSince Spring is right around the corner now is the best time to get your cars ready.
I've been noticing the recent posts about cracks and bad gaskets,babbitt issues and so on.
I figured now more than ever would be a good time to get the word out.
Since there are always new people coming into the old car hobby I wanted to share some of the things we as engine rebuilders have been asked over the years.


What got me thinking of this is as follows.

We received an engine today done recently by others in the North East, has 1200 miles on it and customer complained of excessive oil loss out the back and through the breather. said he had to take it back twice to have the babbitt repoured but the leak still existed.
He then brought the engine down to us and we documented what we found.
Poor work ,bad babbitting,dirt,inferior quality all around on and on.

Since seeing this and the anquish of the customer Spending $3000 dollars and getting a 1200 mile engine doesn't seem like a good return on an investment to me.

I have compiled a list of things to ask your future engine rebuilder.

1)Do you do the work in house and if not who does?
2)how do you clean the engine and parts?
3) do you magnaflux block and parts,pressure test?
4)what babbitt do you use?
5)what machine work gets done on the block and why?
6)do you replace the valve seats and how many?
7) what parts of the block do you remachine?
8)do you balance the engine?
9)what parts are provided in your engine rebuild?
10)do you resurface the flywheel? there is a exact mesurement of steps.
11)do you regrind the cam and what grinds do you offer?
12)do you rebuild the oil pump?
13)do you replace all the hardware int he engine studs,bolts ,nuts?
14) do you repaint the engine is it factory color?
15)do you install adjustable lifters?
16)what makes you different than the others?
17) do you have references you could provide?
18)how long does it take you to finish the engine?
