Q:How do you change valve covers on a 1995 firebird ?
I would recommend taking it to a shop if you have to take off a intake. There can be some major problems that can occur like water going into the oil and messing up your engine if you dont seal it right, i would hold responsible the person doing the work.
Q:Proportional valve problem?
If you are not familar with brakes I wouldn't suggest tackling this job yourself. You will need to take the line off in question to condemn either the prop valve or the line. I have never in my life seen the line itself leak but I guess it's possible. The valve is a dealer item only, whatever you do, dont buy it from a junk yard. After replacing the valve, if that is what the problem is, most likely you will need to get a brake power bleeder to get all the air out of the system. I would estimate through a shop and the typical mark up on the part, shouldn't be more than 200-225 parts and labor including the brake flush, good luck.
Q:how to repair a sprinkler valve?
Yes easy fix-- go to your big box store with the old valve-- so you get the right size and buy a new one less than $ 40.. chances are with the freeze the plastic parts cracked when the water inside froze---
Q:Are valve cover gaskets easy to change?
least confusing to purely do away with the valve hide thoroughly and then there could be adequate of the broken bolt left to get a pair of vice grips on it and unscrew it out, pass to factors shop and get a clean bolt and a clean valve hide gasket and reinstall.in case you tension the motor vehicle the way it incredibly is it may leak slightly oil around the broken bolt.
Q:How does an on-off actuator and ball valve connect?
it is going to be to long of an answere to bypass by, yet you have a often closed valve and a often open valve. So while air is provided, one opens and the different closes. you may artwork something out with that based how your set up is going to be. it rather is the solenoids i'm talking approximately.
Q:Multi Valve advantages?
Think of an engine as an air pump - obviously, we want the least amount of restriction for the incoming air and also the least amount for exhausting the compressed air. The ideal situation would be to remove the head during the intake stroke and put it back on during the compression stroke, but, obviously, this isn't possible. On a naturally aspirated engine, the intake is the most critical because the air is moved only by a relatively small difference in pressures. The exhaust stroke, on the other hand, is aided greatly by the super heated temperature and rapid expansion of the gasses. Two intake and one exhaust valve seems to be the most practical and efficient solution - adding more vales means smaller valves and an increase in the overall complexity. I seriously doubt that Maserati ever abandoned ANY automotive idea due to cost restraints. It's far more likely that adding more valves than three or four simply resulted in diminishing returns. Sometimes the allure of a new buzz phrase is nothing more than a marketing ploy - a 16 valve, DOHC, four cylinder engine, for example, is a pretty impressive resume for an engine, regardless of whether it actually is the optimum performance set up or not.
Q:I can't fix my 3rd valve slide! Help?
Be sure that it is aligned correctly when you place it back in the valve casing. When you are putting it back in, it has to turn until you hear a click, indicating that the valve guide has fallen in the right space. This aligns the valve with all the ports. (The valve guide is a small plastic piece located under the valve spring. This valve guide must snap into a little notch inside the casing. When it does, the valve will be perfectly aligned. You will know when the valve guide is in the right place because you will feel and hear a click and the valve will not rotate any longer.) After thorough cleaning, oiling, and correct valve placement, if you still notice it sticking, take it to a repair shop to have it chemically cleaned. They are typically very good and will ensure your trumpet is in proper playing condition.
Q:Are OHC valves generally smaller than pushrod valves?
OHC generally have 2 small valves instead of 1 large valve operated by a push rod. The aim is to have the most flow possible and the least mass of valve. (avoid valve float) I cannot say anything about specifics
Q:Integra Valves Ticking?
The valve lash is supposed to be adjusted like every 60k. Your's might need it bad.
Q:What parts are needed to fix three burnt valves?
Burnt valves or, far more likely, bent valves. Either way, you'll need to basically overhaul the top end - you'll need to replace the bad valves and the top end gasket set along with any machine work that may be necessary. Estimates will vary greatly from facility to facility and also from different areas. To get a valid estimate for your locality, you need to get local estimates.
