This video was very helpful ? as I am doing a complete rebuild on my very first egine unassisted.. Thanks
I got this dvd from a mentor. It is a good one, but It does not offer any explaination of these components or what they do which is what I need. I think you should know something about automotive engines before hand. But? it is a good dvd otherwise
if u over tighten the valve by 1/4 turn will that? affect the timing at all,,thanks
Didn’t know youtube? allowed commercials.
effects of engin change on the transmition? i changed my diesel 2400 engin with 2400 petrol engin but? kept the transmission same .on my mitsubishi pajero 88 three door ..
@Psi4tsi Whoop, need to stop posting late at night. Sorry bout? that. I have an OHV in the truck and an OHC in the car, and since I’m always working on both of ‘em (and they both have misfiring cylinder(s)) I tend to switcheroo.
@SchizoFilms theres no pushrods in? an OHC engine. The Camshaft itself is was opens the valves.
how much does it cost to replace? a broken valve in nissan altima 1998 model ?
how much does it cost to replace a? broken valve ?
@cranemaster844
2 turns of the crank is 1? turn of the cam.
Hi, I just created this blog to share information about buying used cars. Please visit? us at i2list.com/usedcars.php.? Thank you.
“rotate the engine about a quarter turn” (for the next cylinder on a V8)
“you’ll only? have to rotate the engine once”
Math?
so if im thinking right, you adjust? to zero lash then give it another half turn?
Very well done,? and easy enough to understand for the even a beginner! Great job guys!
So, what? about Overhead Camshafts?
What vehicles have non adjustable rockers with hydraulic lifters? What is? the advantage to having an adjustable rocker with a hydraulic lifter? Are there vehicles that have a dual over head cam design where the cam lobes sit directly on the hydraulic lifters?
@ktmboy1989 … 90 degrees or 1/4 turn for each following cylinders… the? crank must be turned twice for each one full revolution of the cam
@lakeboy36111 …
1 – note #1 plug wire position and pull the distributor cap,
2 – rotate the engine to #1 TDC (rotor @#1 and timing mark on balancer @0deg,
3 – adjust i&e rockers to 0 lash then add 1/2 turn,
4 – rotate the crank? 1/4 turn (90 deg) and watch for the #8 i rocker to drop and stop then adj i&e rockwers to 0 lash then add 1/2 turn,
5 – repeat and adjust cylinders 4-3-6-5-7 and 2, in that order. You will only have to rotate the crank a total of 630 deg (1-3/4 turns).
Finding this “zero lash” position by feel is influenced by too many variables which allows a degree of inconsistancy.I’ll pass on a tip that was shown to me by Barry? Seton in 1985.Adjust the valve clearance to 5 thou.,then turn the the rocker nut down 3/4 of a turn.Thank you for reading.
@BoxWrench good video, but I did it like hoe you explain and it was too tight engine would even run i ended up doing it as the engine runs? loosen the nut untill rocker chatters then tighten it till it stops chattering then an extra 1/4 turn. runs real smooth now.
@ktmboy1989 don’t determine the valve opening events by rotating the crank only.
You should watch the pushrods, rockers or lifters to determine when the valves are actually opening.
If you want to adjust lash on an engine that has the heads bolted in place already…just remove the valve covers and you can watch the pushrod ends and valve tips as the opening? and closing events happen.
@jujutube123 This is the correct procedure for taking a hydraulic lifer to zero lash and then adding the required pre-load to the lifter. The pre-load is set by turning the rocker nut down the extra half turn after reaching zero lash.
With solid lifters, you go to zero lash with a specific feeler gauge between the valve tip and the? rocker. For hydraulic lifters, you need to do the procedure described here, including the extra half turn.
is the diagram at? 2;48 the same as a chevy 350
@ktmboy1989 A quarter turn is correct, since the crank rotates twice to complete? a full firing order. The camshaft rotates at half-crank speed, so 1/4 crank turn = 1/8 cam turn = next piston tdc firing.
I am having a problem in adjusting 2 of my exhaust valves on 1999 Honda CR-V. I can screw the adjustment up and down but it does not provide any clearance.? I could adjust all intake and exhaust valves with the exception of the two exhaust valves (One on number 3, and One on number 4). Any advice, thanks!
