Ø      A ensures the engines internals are functional and the engine has a good "vacuum" draw to it. If the engine has a low output of vacuum pressure (in pounds) then we know the engine has internal damage and needs attention or rebuilt.

Ø      An is done when the motor is warm and cold. When an engine takes a front end shot; it can push the cradle into the oil pan. The oil pressure test ensures there's no damage to the oil pump or lower internals of the block.

Ø      A is done to make sure there is no damage to the heads or block. If a vehicle takes one on the front of the block it can damage the crank. If the harmonic balancer is even just slightly hit, it can wipe out the whole lower end. The C.O. check will tell us if there is damage there.

Ø      We will then . We drop the trans pan to inspect the trans fluid. This is done to make sure there is no metal or burnt fluid in the case. If there is any metal or brass collecting we will send it for a rebuild. For manual transmissions, we run the car through all gears and check to make sure engagement is smooth like it should be.

We do a compression test on each cylinder. A engine from a roll over vehicle will run "perfect." However, if someone tried to start it before the engines top half was properly drained, there is a likelihood of damage. If the oil was not drained, the extra oil in the upper half will cause friction and the push rod most likely will crack in the engine. The motor will still run great, but it will have a dead cylinder. A compression test will show if any of the cylinders have damage.
