Ive just started to strip down the series 5 turbo 2 motor im planning on fitting into the bug.
I thought it would be a good idea to try and document the happenings during the engine rebuild so i will be getting some pictures of it all shortly. I am by no means an expert but am willing to learn and figure it would be an excellent way of trying to help others out if they are in a similar position: to rebuild or to buy reconditioned.
Its on the workshop bench as we speak and is now in a state that i would consider ready for parts collection and rebuild.
jitesh (one2watch) and I have followed the engine from the point at which it was dropped from the car to the stage at which we are at as we speak. I thank him for his help and correspondence throughout.
Right...so the questions. Having removed all of the parts, i discovered not one, not two, but THREE broken corner seals. What is likely to be the cause of this? Most of the parts seemed to be present (no little peices \'missing\') and thus i hoped the intermediate and end housings would eb OK. As it happens i beleive the end housing is screwed (picture to follow) as there is some scoring to it. how much is allowable?
Further to this there is a slight amount of pitting on the intermediate housing which is very fine....but is it acceptable?
One rotor housing seems good.....no scoring, no serious chrome recession...the other has some scoring and more considerable chrome recession (again not considerable though) what is acceptable here? how much should i pay for a decent second hand one?
I also beleive that the irons may have been ported. Looking at the end irons there is a small \'ground\' edge around the inlet and the edge is not exactly straight from the leading edge of the port to the trailing. Pictures to follow.
What about wall thicknesses? What coolant all thicknesses would you consider to be acceptable? The do vary on these irons but it doesnt seem too considerable...what are the specs?
Are 13b REW irons the same as turbo 2 irons? and indeed housings? do they differ?
How much can be taken from the motor with buffing the irons? How do you copensate in terms of latteral play?
Thanks in advance for your help guys
