Costs

The overall costs of parts were a major consideration before any work started. I reckoned on having to spend at least £500 re-newing the timing chain and associated parts. I never thought I would have to do any other major work as these engines can keep going well into 200k.
Even just doing the head gasket and timing chain was never going to be a weekend job, even if I had the money, so, first thing was to buy another car so I could take my time to decide exactly how I was going to tackle the work ahead. This immediately set me back around £500 to get a Cavalier bought taxed and on the road. I should be able to get this outlay back in a couple of months anyway.

After pricing second hand engines and re-con engines, the only sensible option for me was to do the re-build myself. I'm not a mechanic and the thought of working on one of these engines had always scared the hell out of me, but, I had no choice. I have done an engine re-build many years ago so I had an idea of what was ahead.

I needed to find someone to do the machining work. I would have liked to have gone to someone who had already been used by another member of our club, however, not many of us have had to go this far yet.

I first visited a machinist called Jenkins Motor Engineers based in Whitton, just off the end of M3 in London. They are a member of FER (Federation of Engine Manufacturers) and they seemed to be quite well known by the auto traders in the local area. I also visited (by coincidence) another Jenkins machinist in Farnborough, local to me. This would have been easier for me but the guy was not very interested in doing the job, quoting stupid prices and basically trying to frighten me away by saying how much parts cost, at one point I remember him saying something like 5 grand for a re-build ! ha, I walked away. It turns out that both machinist's were originally owed by the same company until they split some years ago.

I took the head,block and crank to the Jenkins in London. I was looking to have the head welded and skimmed, the crank re-ground, block honed. Mick had given me an idea of cost's the first time I'd spoken to him and we talked about various options. At first I was just going to have the block honed and fit new rings, however the price for re-bore with new pistons and rings was only about £200 more,so, I was now undecided . I left the block with him so that he could measure up himself and make a recommendation later.

After seeking advice from Ian Marsh I decided for just the hone option, I could ill afford to spend £200 if it was un-neccessary.

The following table outlines the cost's to date, all prices are subject to VAT.
Vauxhall prices are based on the Autobahnstormers negotiated club discount.
