- Q:what exactly causes a valve to stretch?
- All metal bend and even wear down. Valves don't stretch. They wear down. Good Luck...
- Q:I am being sent for a level 2 Ultrasound Thursday because my previous US showed one of the babies valves was enlarged. She said all 4 chambers were there but she was very vague on what this means. Care to shed some light?
- ?UPDATE? We went to the US today and the heart was 100% HEALTHY!! There was nothing wrong with any anatomy of baby girl. The doctors there said they are completely confused as to why my Doctor would tell me the baby might need heart surgery when she wasn't even 100% on the issue and even if it was due to positioning like she 'claimed' at first, then a Level 2 US wouldn't be necessary. I'm just so grateful and thank God that my baby is ????!
- Q:.The valve behind the toilet is spewing water (we have connected a hose to it and have it emptying into the tub). When we try to shut the water off from that valve, the knob or turny-thingy (the name escapes me right now) just turns and turns correcting the water flow slightly, but not shutting it off.The problem it that we can't find the main water valve outside the house. What am I looking for please?!? Also, we shut a valve off in the garage, but it was for the hot water.Help!
- find the house water meter located a the edge of the street in your yard and turn the main valve off
- Q:Tryin to figure out how many valves a 1992 vx has. 16 or 8?
- '92 Civics had single overhead cams (SOHC), so they have 8 valves. 1 intake valve and 1 exhaust valve per cylinder, so since there are 4 cylinders, that makes 8. Vehicles with dual overhead cams (DOHC) had 16, but Hondas had SOHC cams at that time. I'm really surprised how many people are saying 16. That is incorrect. I am positive. You cannot have 4 valves per cylinder (total of 16 valves) on a motor that has a single overhead cam.
- Q:I have a 1997 Toyota Corolla. My check engine light has been on. I tried to get my car smogged and it failed. I then got an oil/air filter change and just yesterday I replaced the EGR valve which was the result given after 2 diagnostic tests. The mechanic gave me my car and the check engine light was off, I've only driven about 5miles and the light is back on. I have to pass smog asap to register my vehicle. I plan on calling the mechanic back and telling him the light is on, but could it just be a sensor?
- it could be a sensor ! the EGR code probably showed up because a sensor was interfering with the valve !
- Q:my mechanic did a valve clearance check and said it was OK and when I asked him about the clearances he said that they were 6 thousands and 9 thousands however in my book the measurements are different they are as follow: ( i don't understand what he meant by thousands)inlet: 0.10~0.140.15~0.19 exhaust: 0.14~0.190.20~0.24so did he just make it up or did he get the wrong measurement.
- Your guy was quoting clearances in thousandths of an inch: .006 and .009 or 0.15 and 0.23mm The spec in your manual is given in millimeters. Your exhaust valve clearance is at the upper end of the range, right where you want it. The intake is at the low end of the range. Clearances tend to tighten up as the valve seat wears with use. It's not clear to me why your book would have two specs for inlet and two for exhaust. Clearance specs are usually given for a cold engine. Perhaps the tighter spec is for a hot engine. Bean, I'm right about the whole thing. Valve clearances get tighter as the engine warms. They typically get tighter over time. If they get looser, there is some unusual wear going on.
- Q:Between these two Blow off valves around the same price, what would be the best choice for a pt cruiser.
- The Mopar Performance blow off valve is really going to be your best bet if the two are roughly the same price. The reason I say that is because the Mopar unit is designed to fit onto that car, therefore it is engineered to release excess pressure at a safe level for that engine. The Greddy unit is also going to typically require modification to make it fit and function properly. Unfortunately, what they don't tell you about universal units is the reason they are universal is because they don't fit anything until you make them to fit, you just have enough material and hardware to get creative with it. If you are looking to extensively modify your engine, then it may benefit you to go with the universal unit and just wait until you have your piping cut exactly the way you want it, this may give you better location or clearance using the aftermarket unit, but otherwise like I said, I would go with the factory performance BOV. If you have any further questions about your cruiser, please feel free to email me, I have had a cruiser for a couple of years now and have also done lots of customizing to cruisers for friends.
- Q:are the carborator reed valves supposed to be open or closed on a 1999 yz 250?dirt bike
- the aggregate is slightly skinny. The exhaust will smoke much less, however the appropriate end will ware quicker then standard. replace the piston rings as quickly as a 12 months could shop the engine risk-free.
- Q:Im trying to replace the egr valve on a 97 lincoln continental. I need to find out what size wrench I need, to get the nut off. Do you know?
- I am assuming you want to replace the EGR valve because you are getting an insufficient EGR flow trouble code. Before you replace a perfectly good valve with an inferior aftermarket part that will likely fix nothing, a little more diagnosis is in order. If you have access to a scan tool and a vacuum gauge, perform a KOER (key on engine running) test on the engine with the vacuum gauge connected to the hose to the EGR valve. When self-test reaches the EGR test, look for the vacuum guage to move during the self test. If it moves, the vacuum source and EGR solenoid are good. If not, trace the vacuum harness for leaks. Without the scanner and vacuum gauge, find a length of hose and suck on the hose, or connect to other vacuum source to test the valve. You are looking for an RPM drop at idle when you open the valve in this way. I suspect your problem is a passageway clogged with carbon. Remove the valve and throttle body to access the clogged areas and manually decarbonize. This is the most common reason for an insufficient EGR flow on a Lincoln, along with a faulty DPFE sensor or related hoses. My money is on the clogged passages or the bad DPFE sensor.
- Q:here are pix's i want to no, if there is a easy fix or does it have 2 b machined thanksi think it use to have a bent valve in it
- There is really no such thing as has to but there is a thing as ought to. You should put good used heads in a machine shop for a clean up and restoration. The worse they are, the more they need new seats, seals, guide clean up with new valves, surfacing and so on.
