I'm 100% positive I've narrowed down the louder valve train noise I thought I was hearing. It's the louder clicking you hear when you first start it up cold, it eventually stops when the engine warms. The decompressor? It's not stopping, or closing, or whatever it does when the engine warms. I'm sure of it after listening to it today, that's the clicking I hear, constantly now. It might explain why the exhasust sounds weird to me as well. Is there anything I can do to check this out, or should I just take it to the dealer for inspection? I don't mind pulling a case cover or two. Is there anything electrical, or is it strictly mechanical in nature?
Hobbydad, you're in Toledo, Ohio? Meet your newest stalker I live in the Old South End behind the zoo.
not sure if this will be of any help though!
Ace:Being the lazy sort of guy I am, I will ask you a question.Does the O2 sensor protrude very far into the gas path?It's pretty obvious that the area where the O2 sensor is located gets much hotter than the exhaust pipe shortly upstream or downstream so I was thinking it might be quite a severe obstruction.If it is, perhaps adding a spacer between the O2 sensor and the bung to move the tip back out of the way could improve the exhaust discharge a bit?
I had a long meeting with the guys at Mondello's yesterday.A variety of approaches were discussed, and I gave them a pretty good budget to do their development experiments with. My instructions were to get the best bang for the buck that they could get, and I didn't limit what they could do with it. Whatever would give the most, is the instruction, as long as it wouldn't put the final price out of range of the buyers.I also stipulated that I'd like to be able to offer at least 2 "stages" of performance, so that people on a budget with modest performance improvements wouldn't be forced into a high price option.One of the biggest things to come out of the meeting was that they think they may be able to get enough flow improvement out of the exhaust port without moving it around, or enlarging it beyond what the stock pipe can take. This is still a conjecture, but they stated that they might be able to do that. It that turns out to be the case, it could save considerable money from not having to buy the aftermarket exhaust pipe. I think the telephone pole muffler will still have to go, in any case, though.I always try to keep the costs down by any means possible, as long as I can deliver what's needed in the overall package.So, we'll have to wait a while, to give these guys some time to work on the development processes. They have the green light and a budget, and if I have to increase the budget along the way, I will do that if it means getting a better result.
