Awesome, I like this! I hope you are successful in creating this monstrosity!

I suspect the camshaft got unevenly worn down because the rocker shaft wasn't exactly aligned as it should be, it was a bit off and it may have caused bad lubrication, warping the #4 exhaust lobe as a result and wearing down all the other lobes. So it turns out that I was too much in a rush in Augus...

Hello guys, it's been a while since I last posted an update to my thread. A few things have happened lately: In September, the old head gasket finally blew as you know. I took some time to replace it and clean up the engine on the inside a bit at the same time. The camshaft seal behind the camshaft ...

Thanks heaps guys, the engine runs perfectly, no "chuff chuff", and it passed MOT emissions tests like a charm! Engine runs smooth and very easy, I don't even need to hold the throttle down as much on highways as I used to do! 8) Here's the old cam (didn't bother to clean it up because it'...

Ok E, I'll take your word for it!

Thanks for your input guys, I have a day off Monday next week. Going to swap out the cam at that time.

Oh! Sounds a bit brutal to me but I'll give it a shot, thanks m8!

Ok, thanks m8!

I replaced the head gasket a few months ago, looks like I can't avoid opening the engine up again...

Hey there guys, long time no hear! I ran into a bit of a trouble; the engine is doing chuff-chuff-chuff at idle (one cylinder clearly coughing but not misfiring) but running fine above 1100 rpm, apart from a couple of misfires here and there. The combustion is clean, the spark plugs stay clean and l...

Is that a "bump"?

Now that's darn practical! You have awesome engineering skills!

Nice!

Blew my head gasket the other day. I was accelerating WOT on the freeway and the engine started to lose power and jerk... I got worried and let off the gas pedal until I felt a stable speed so I could get off the freeway (would have stopped completely if the engine wouldn't have stabilized). I check...

Ok, thanks m8! It hasn't fouled any plugs yet, rather the opposite now that the valve stem seals are replaced. Acceleration has improved too, especially at high speeds. I was cruising on the freeway at 135 km/h the other day, I downshifted to fourth gear and floored it. I hit 160 (speedo needle at 1...

Alright, I believe I have stuffed piston rings on cylinder #3... the spark plug is covered in oil after a cold start... but after driving around for a while it cleans up and looks as good as any of the other plugs... completely normal amounts of soot deposits etc... nothing dramatic at all! I guess ...

Awesome! Gloss black is beautiful.
