- Q: I got my timing belt done on a 1999 Civic Si on September 26 @ 113,699 miles. at 116,9xx miles I bent a valve on my third cylinder. How likely is it that the timing belt is the reason why this happened? I heard that if the timing belt is a tooth or so off, it could bend a valve. So is it likely that this could have happened? Anyway to check?
- If it was a timing belt issue it woudn't have only been one cylinder. And usually if it's only off by one tooth, it just runs poorly. IT has to be off by quite a bit, or the belt has to straight up break to bend a valve,, if that happened it would have made a horrible clanging noise repeatedly before it eventually sputtered out. the 1999 Si revs to what... 8000 rpms? You didn't happen to miss a shift and over-rev the engine, did you?
- Q: The difference between butterfly valve d71x_10s and d341s-10
- Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.

- Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
- Q: Have an iron block, aluminum heads, solid roller lifters, Jessel rocker shafts, what should my valve clearances be cold, and hot??
- Because you apparently have a built engine here rather than a factory assembly which simply has solid lifters, and the data you have is either inconclusive or conflicting then I will recommend the following procedure: Assemble them cold and adjust to Intake .010 and exhaust .020. After firing up the engine, adjust the carb, if it is so equipped, to a smooth rich idle and run it in for a couple of hours mixing idling with moderate load and a few full throttle pulls through 2nd gear to seat the rings. Bring it back into the shop good and hot and set the valve clearances at .008 intake and .016 exhaust hot. After adjusting the valves readjust the idle to 700 RPM and set the timing. initially set the timing at about 2 degrees BTDC until you hav run in the engine, If you are without clear specifications for timing use a vacuum gauge and play with it between 2 and 10 degrees BTDC with the vacuum advance disconnected and plugged, you are looking for the highest vacuum at idle as a starting point. Run it hard including lugging it in high gear at around 2500 to 3500 rpm at or near full throttle, if you are getting spark knock back it down 2 degrees at a time until it does not knock when lugged. If you get no spark knock when lugging it you might try advancing the timing 2 degrees above the vacuum indicated optimal setting but do not go beyond that point. After setting the valves and timing readjust the carburetor to the best lean idle and set to 650 to 700 rpm depending on where it feels comfortable. In the old days a lot of this was done totally by ear - hence the term engineers. Today I think most holders of that revered title do not have a clue where the term came from.
- Q: I have a 1993 Oldsmobile Cutlass Supreme and I think I have the case of the blow-by. The engine had high mileage, but was rebuilt b/c it stalled while driving. 3.1L V6 gasoline engine. The fuel filter and the fuel pump are brand new. Now we have the same problem a few months later. It stalls while driving. Its been sitting a while and won't start by itself, so I pulled off the air intake hose off of the air filter to spray starting fluid into it. I noticed oil puddled in the air intake hose, so I looked for the PCV valve on the rocker cover. There is a tube going from the air-intake hose to the rocker cover. I popped out the tube from the rocker cover and there is no PCV valve. Just tube. Is that where the PCV valve is supposed to go? If not, where can I find it on the engine? And could that possibly fix the blow-by and the stalling engine? I'd appreciate any help. Thanks in advance.
