a 253 went into my car before the engine in there at the min, it had been sitting around for 11 years. car had rusted around it. and engine looked very dirty. but it was a very smooth runner. soon as it went in mine and was all plumbed up, and a minor service, started very easy i also tried to destroy that engine before it came out, my old trimatic died. but the engine lives on! it liked doing circles in the paddock! it did however have a lovely leak from the sump gasket.
