- Q:ducati valve adjustments?
- Well first, you need to get them inspected, and they'll only adjust the valves if it's needed, even at 6k mile intervals, if your valves are still in spec or very close without lobe drag, they probably won't be changed, so check your bill and ask your tech directly if they were changed, some less reputable dealers may try to pull a fast one on you. If you actually needed ALL 16 shims changed, you're easily talking $1000 in labor, esp. on the 748/916 style heads, which have access ports on the heads instead of being able to remove the whole top of the heads like the newer DESMOQUATTRO heads, and are a PITA to work on because of it. The bad thing is that until recently (and they still need improvement) Ducati's quality control is lower than other manufacturers, meaning very inconsistent performance reliability, just from variances in manufacturing. If you get a GOOD tech to do the bike right in the first place though, not just valves but all-important TPS resetting, cam timing/belt tension, and balanced CO's in your exhaust, you will have a lot less headaches with your Duc.
- Q:how can I buy a useful ball valve？?
- what okorder.com a stopcock is a screw down tap same system as household taps ball valves turn a ball shape inside with the opening inside no washers required and they are in the u.k. as well.
- Q:99 Eclipse Valve Cover?
- You can have it dipped in chrome and detailed for the lettering. It pricey but its the best way or you could try finding chrome spray paint that is good up to 500 degrees and do it yourself but it may not look as good.
- Q:Solenoid Valve Control?
- See okorder.com/
- Q:All the Valves of the Heart?
- There are 4 valves on the heart. Right atrium Left ventricle Left atrium Right ventricle. The atriums are the top of the heart...the more smaler ones and the ventricles are th larger ones which are below the atriums.
- Q:Is there a difference between the two valves in each side of the heart?
- Yep - the right atrioventricular valve, also called the tricuspid, has three cusps. On the other hand, the left AV valve, also known as the mitral valve or bicuspid, has two cusps. The bicuspid can withstand more pressure than the tricuspid.
- Q:I was adding air to my bike tires and the valve became loose. Do I need a new tire or is there a way to tight?
- It sounds as if you just need a new inner tube if there is a valve problem. New tubes cost only a couple of £££ each, and it's worth getting a couple of spares and a puncture repair kit if you don't have one. If you have some mates who also cycle, it can be worth getting a box of inners and splitting the cost. That way you get the discount and some spares. Check that you get the right size for your tyres.
- Q:Diverter Valve issue on a 2000 passat
- Yea... The 1.8T is made so you have to recirc your dv. You can run a BLOW OFF valve off of your throttle hose, but thats a lot of redirecting and work for some silly extra noise. Chip that Passat to get some more turbyturbo noise. Y was there a stock golf with a dv? I'm confused...
- Q:Trumpet valve problems!!!?
- When dealing with complex and artistic things such as musical instruments, ALWAYS buy form where you can trust, and preferably from where you can test the item out.
- Q:97 Escort. Trying to prevent the dreaded valve dropping. If I maintain the engine colder could the valve hold?
- I'm aware of the Escort/Focus valve seat problem. I bought a Focus that dropped the seat. Ford installed faulty seats when they were new. The only fix is to take it apart and have all the intake seats replaced, preferably before one drops. The seat shatters into a lot of pieces and jams between the head and the piston, bending the rod and usually shattering the piston. We can deduce that it was faulty (incorrect heat treatment) from installation because exhaust seats endure a lot more heat and abuse, but they never drop that I am aware of. I have seen seats come loose on other makes and they stay in one piece. Ford should have recalled all Split Port engines and redone the seats free of charge. But, their opinion is that an engine that makes it 100,000 miles is considered a good lifespan, even though my Honda's regularly exceed 300,000 miles and still run like new. There is little one can do to prevent this failure except to preempt the catastrophe by pulling the head and doing the seats. This reduces the eventual bill by nearly 50%.
