Mixing and matching Bosch plungers and heads
#1
So simple enough question, I have about three 9mm heads, plungers and collars, all kept in diesel, but all are mixed up. Now I seem to remember that they're all supposed to be matched to each other.

So should I try fitting a random combination anyway or just find another 9mm head from somewhere?

Id find a matching set if possible.
You could either end up with a a seized plunger in the head or shite performance. Neither is an attractive option.

Yeah, and after 100k or so of driving, it'll be pretty well machined to only one head... If you really start spinning the engine fast, you're quite likely to overheat it and it'll sieze and all the fun will stop quite rapidly.

Cheers guys, I suspected that might have been the case, and after looking in my bucket of bits, some have started to rust even though they're stored in diesel Huh
I shall have a look locally, otherwise expect to see a wanted add shortly!

If you have all pieces, clean them up with some fine wire brushes and slip them back together. If theres diesel there I doubt it'd take that long to work out which ones from which based on how they all feel when the plunger is pounding head. If ones loose, ones tight

Id be tempted to do that, but unless the difference is obvious id advise against using it. I cant see the difference being obvious unfortunately.
