SOURCE: upper end gasket replacement leave it to the pros

I'm not going to say that the average joe can do the job but the skilled amateur mechanic that understands the basic principles of mechanics should have no problem.

Basically, it's pretty simple. Have the piston on that cylinder at Top Dead Center so that both tappet are all the way down. Don't mix up the pushrod as they're different lengths and color coded. Any you need some good torque wrenches that are in inch and foot pounds. One of the more difficult areas is getting the upper cover bolts out of the left side. Clearances are close unless there is a hole drilled in the frame which I think Harley did in the later years.

SOURCE: how difficult is it to

FIRST you need a service manual. You can't just put in a new valve, The seat needs to be resurfaced & you need some special tools for that. You will be best to pull the head & take it to a shop to have a valve job done correctly, But if you follow the manual exactly, You can save yourself a couple of hundreds. The big question is WHY did it bend a valve ? Have the shop help you.

Top end engine noise-valve train?


You may be coming up on the maintenance interval for a new Belt, but I would imagine that this vehicle has VVT, variable valve timing, and that you may need an adjustment on that as well.
Valve noise is most likely what you are hearing.

I HAVE A 2003 MAZDA PROREGE ...I PURCHASED IN NEW...I,VE TAKEN GOOD CARE OF IT THRU THE YEARS...IT,S STARTING TO SMOKE WHEN I START IT UP IN THE MORNINGS FOR ABOUT A MINUTE THEN THE SMOKING STOPS...DOES'NT...


There is always a better alternative than the dealership as far as costs. They want to put a new motor in a 2003 model? That is ridiculous to me- cost-prohibitive. Find a reputable independent shop. Look for references and customer satisfaction. A used, low mileage replacement engine is a better alternative, probably less than half the cost of a new engine.
There may be an even better alternative, where you refurbish the top end of the engine-the cylinder head and valve train. This is dependent on that a wet-dry compression test supports rebuilding the top end. What I mean by this is a compression test of the cylinders reveals low compression in one or more cylinders, okay. Next, they would squirt some oil (about a tablespoon) in the low cylinders and check compression again. If compression doesn't change, it points to the valves and valve train (the valve guides which wear and could let oil into the cylinder). But if compression is higher in the wet test, then the piston rings are worn and losing compression, and oil gets past them-this would indicate the engine needs a complete rebuild or a replacement is called for. The reason for the wet test is that the oil will temporarily seal around the piston rings and improve compression if the rings are the problem.
If the test shows the valves are the problem (and it is very possible on an engine with only 120K-your bottom end could be fine), then a top end rebuild of the engine is a much cheaper route than any other choices. You may not know this, but often a little oil burning in the cylinders at start-up is nothing more than the valve stem rubber seals are deteriorated-a real cheap fix. The dealership probably won't tell you this. However, with the loss of power, well, that points to something more severe than valve stem seals. So I would recommend the wet compression test, just to check if it is the top end or the bottom end. If it's the top end, you could have the cylinder head reconditioned and motor along for a few more years, trouble free.
Similar to a compression test, a "leak down" test of the cylinders is actually a more accurate method of finding where compression is lost, and it's only a one step test. They hold compressed air in the cylinder and analyze where it escapes to pinpoint compression loss. Loss of compression translates into loss of power. Have either test done before you decide. Find a good mechanic and trust his advice. (Stay far away from dealers. Greed is their motivating factor.)

To drain the transmission, look at the chrome end plate on the transmission that the clutch cable runs into. This is the clutch release mechanism. Just below this, in the center the plate the chrome one bolts to, is a drain plug similar to a pipe plug. Remove the plug, transmission drains. Refill the transmission with 20-24 ounces of transmission lube.
