Hi all,
I think my 86 TM has developed it's death rattle ...
When cold starting there is a metalic rattling on the near side, that takes a minute or two to subside and stop. Usually happens in the morning, but also sometimes when the cars been standing for most of the day.
Having read a few threads and looked in the Haynes, I decided it was the Balance Shaft chain, and had a go at adjusting it. I slackened Special bolt B a little, and was able to move the Projection up and down. It was however already fully down, hard up against the casing. Put it all back together, started the engine up and discovered that the rattle was now constant:(
Readjusted, ie.slackened everything off, gave it a wiggle, put it all back together, same result.
On the third attempt, I loosened Special Bolt B a few turns, till the projection, and some kind of plate behind it, got really loose. I had read the warnings about undoing the bolt such that bits drop off behind it and fall into the engine, and that didn't happen. Put it back together and now it's kind of back to where it was ie. a minute or two of rattle, till, I believe, it picks up enough oil to keep itself lubricated.
I'm wondering if anybody has an opinion on how long the car might go on like this? Is it particularly dangerous to keep using the car? What happens if (when:) the chain breaks or gets so slack it falls off a cog?
I'll try using an 'older engine' oil next change in the hope that it'll stick around a bit more, but other than that I don't really have the time or equipment to replace the chain or guides, which I believe involves taking the engine out. Any clues on how much a mechanic might charge for the job?
There's a few things which need doing on the car now, and the last mechanic I saw advised me to just keep driving it 'till it dies then get something else:)
Thanks in anticipation
