Dismantling a 71 vw 1200 engine Part 2

Back in april... after getting the manifold nut removed i proceeded to soak the bolts which are holding the silencer onto the exhaust manifold... i will need to remove the silencer box so that the whole exhaust and heater box assembly can be removed.....

Before i go into the details... im sure you wld have noticed that the title has 71 written on it instead of 65 ... well i knew that the engine had been changed in my car by the former owners but i never bothered to check the age of my engine.... after checking the Vin number i found it to be an engine made in 1971.... and looking at the number of Brazilian parts on the engine... im guessing it was poorly overhauled.... well maybe not poorly overhauled but definitely not a top overhaul anyway back to dismantling

After soaking it for a week it still did not get loose... i kept soaking it and hitting it with a chisel and hammer hoping it will loosen up ...but nothing... i tried to get a closer look... and found what seem like both the male and female connections had fused together with rust.... then i thought hmmm i might else well put a new Scat system or something like that... basically a new exhaust assembly..... i wanted to keep the heater boxes so used my angle grinder to cut the very tip of the silencer off... as shown below..... as soon ass both sides were cut, .... the whole assembly the came apart easily....

Below is the exhaust assembly.....

Engine looking a little smaller.........

After looking over the engine for no apparent reason.... taking shots in between as i did..... i found a bolt which was missing a nut... its something which is connected with the distributor.... hmmmm i wonder if i had driven 5 years without it........ or did it go missing when my mechanic replaced the contact points and serviced the distributor..... back in 2003??

The bolt is for holding the distributor clamp (as you've probably already found out.)

Sometimes during engine disassembly, somebody might remove the distributo this way instead of loosening the clamp and taking off the distributor, this avoids disturbing the timing and having to retime it later.

What's promoting you to disassemble the engine? Oil leaks? Or just having fun? (I do that too sometimes)

By the way, do you know of any chopshops etc that may have old/broken beetle transaxles? I'm currently looking for these. If you have any leads, do contact me at li_gangyiATyahoo.co.uk (Trying to avoid spam bots here, replace AT with @). Thanks in advance.

yes i figured it was holding the distributor clamp but i didnt know that in doing so... one can avoid disturbing the timing...

my engines pretty much shot... i suspect i was driving with only 3 cylinders... so i thought i would have fun dismantling it... and learning more about it.... im looking at overhauling it myself... but first i will see if the engine is worth saving... since it is not the original engine that came with the car from the factory... if its not worth it i'll just put in a new engine...

i will let you know if i get some leads on old/broken beetle transaxles .... thanks for stopping by..
