So please learn from my mistakes... Here is what happened... Bought a JDM Motor from JDM Engine Depot a 5VZFE 3.4L. Got the engine, started taking it apart and when the intake came off the backs of the valves were all rusty and covered in what looked like mud. One head was removed and there was a good bit of water and mud like substance in it. Probably from a tsunami. Called JDM Engine Depot and told them. They said the warranty is void because the head was removed. and even if the head was not removed i would have had to pay $500 to ship the bad engine back and to receive another engine. (That was possibly bad as well lol) I said this engine is obviously bad with mud and water in it it doesn't matter if the head was removed of not. This is obviously wrong not to warranty it. The person I talked to said to bad. I said I am going to tell everyone I possibly can that JDM Engine Depot will not stand behind their engines and not to do business with this company.
