Sorry, should've answered these to 'all' before... -----Original Message----- From: Erkson, Toby [SMTP:toby.erkson@intel.com] Sent: Tuesday, April 27, 1999 8:41 AM To: type3@vwtype3.org Subject: RE: [T3] Tune Up & Brakes Use a higher octane fuel, like 91 or 92. <<<92 is the lowest my car has seen since I met her. The lucky bastards in Texas can get 93 at some gas stations. <<<In NJ at Sunoco, you can get 'Ultra' which (was) 94.5. Is the engine CLEAN? Years of dust and oil can collect on the cooling fins and around the oil cooler <<<The engine is dusty (I live in a desert), but otherwise clean. I have not had the shrouds (tins) off, so I don't *know* that there's nothing in between the cylinders, but based on^1aª the rest of the engine looks, I'd bet they're fairly clean (especially based on the fins I *can* see). . Is the cooling system fairly air tight? <<<Aha! I knew I was clever, here. I checked all the fittings, and there didn't seem to be any gaps or significant leaks, but... Are the hoses connected between the cooling fan shroud and the heat exchangers? <<<Do you mean from the back of the J-tube to the heater channels under the doors? If that is the case, I *am* missing the one on my passenger's side. I didn't even think this would be a problem, as it's past the engine itself. Is your timing advance SYSTEM working correctly? <<<Tested the vacuum advance and nicely held 15psi steady. Mechanical advance *appears* to be working, and it idles level. Are the spark plugs clean? <<<No black, just a trace of orange on Bosch Platinum 'Guaranteed for 100,000 mile' plugs. Otherwise very clean. This is how it stands. HC at idle Sunday, immidiately after all new parts and such: 232ppm, yesterday at emission: 499 (out of 500). CO at .19 out of 5.50 (both days). What do ya'll think? Or should that be all y'all? It was probably only 65¼ Sunday for the testing, and 90¼ at DMV. ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
