Starting my first attempt at replacing an engine. The car is a 2009 Pontiac vibe 2.4 toyota engine. I almost have the old engine out and have bought a salvage yard engine. The donor car was a 2009 vibe that had rear end damage in an collision 115,000 miles. I have the engine home and trying to do some testing to make sure I want to put this engine in the car. So far it looks ok, rusty oil pan etc. however I’ve done a few leak down tests and I’m not real happy with the results.
#1 25 % loss out exhaust valve
#2 40% loss out of cyl #1 and some from exhaust valve
#3 35 % loss out of exhaust valve
#4 30% loss out of exhaust valve and cyl #2
The engine has been out of the vehicle for a bit of time and dry. My first test was worse but got better after turning the engine over with air blowing through. I then added a little oil to each cylinder and turned it over a few times. that’s when I got the results above.
Like I said this is my first engine swap and I didnt know what a leak down test was two weeks ago. when testing the cylinders are at TDC and I don’t think they are moving after the air is applied.
I have a 30 day warranty on the engine. Ijust not 100% confident in my testing
Any advise is appreciated thanks in advance
