Never Give Up.... π’
We had the TVR back in for the blowing manifold gasket. The plan was to replace the 8 however it soon became apparent that it was not going to be. 16 mild steel bolts screwed straight into the alloy heads. Some corroded to the point of having hardly any heads on them. It was decided to attempt changing just the one that had failed. This should have made thinlgs a bit simpler. Little did I know what I was in for. Firstly, there was no way you could dare shear the bolt, or round the head as the engine would have to come out which would probably involve lifting the body off the chassis I think. The top bolt came out as it wasn't particularly tight. Probably the reason the gasket had blown. The bottom one was a different story. Call me patient as it took 6 hours to get it out. Genuinely. A few degrees back and forth stealing a degree at a time. Heat, release oil, heat, release oil. In the beginning a 9/16" spanner, being levered with a bar. As the head became worn we moved onto a 14mm. Gave the bottom of the fl**ge and the head a good hit with a blunt chisel hoping to make it a bit looser, to no avail, so it was just perseverance π A major result finally getting it out. Now the manifold web had to be cut to free the front pipe. It being nearest the collector gave us little movement to get the old gasket bits out. Then a screwdriver was wedged between the head and fl**ge after levering some space with a large bar. Slipped the gasket in from underneath, got the bottom bolt in and flipped it around to the top. Back on it with the bar, screwdriver out and pushed it round the rest to get the hole lined up with the top bolt. A final tighten up followed by a start up. I was truely terified incase it hadn't resolved the issue but success. What a job. 7.5 hours for two bolts and one gasket. The design is ridiculous. Zero space and steel bolts into alloy subjected to extreme heat. Studs and nuts would've been the answer. At least they could be split with a chisel if siezed. An absolute nightmare of a job. Saved a fortune however given the alternative... π
