That's the same thing that happened to the water pump that was on my TDI when we bought it... didn't think to look at the brand...didn't think there was such issues...wish I would have now. But the difference is the one I bought played nice and only evacuated the cooling system
Yeah, the soot will accumulate in short order.I'd imagine that if I clean the tops of the pistons that they will just get sooty again in one combustion cycle.
Andybees I'm working on my first Vanagon, 86 Syncro and boy would I like to put an ALH in it. The owner bought another 2.1L that we installed but from GEX...
There could be a couple of factories. Hard to say. Economics would suggest they're be at least two until the demand for pumps went down. Definitely you can have several brands all made from one place. This is common throughout all industries (clothing, electronics, etc).I bet all the water pumps are made at the same factory and just labeled with whatever they want to call it today. I am an engineer and I have seen that in action.
Doubt it but I'm sure there are some common factories for the aftermarket ones.I bet all the water pumps are made at the same factory and just labeled with whatever they want to call it today. I am an engineer and I have seen that in action.
Any complaints so far? What's there to worry about?Shoot I've installed the stamped metal pumps in three cars over the past year, now I'm worried about it.
That brass looks pretty nice. The cast looks really shoddy, poor vane definition and port holes.Below, all from ALH engines... Brass, Plastic and Cast ... (sorry about the focus)
I've had no problems with the previous kits nor any of the many people who i have installed them here locally. Maybe a bad batch from a particular manufacturer. I couldn't tell what brand mine was.Nope, impellers are not the problem. But, it is quite interesting to see the array of impellers in use.
Seems the WP that locked up in my engine come from IDparts as well. There's only two vendors that I've purchased kits from in recent years and it has been a long while since purchased anything from the other one.
Found the info I need.Thank you who recommend my service. I appreciate that.
What should or should not be replaced; I'll speak from experience....rarely do we replace every single valve... and that is in thousands of heads produced in our shop. Virtually the only time all valves get replaced is if they are all bent. Otherwise, it is rare that a valve is rejected due to stem wear. Our success rate declares our position.
Valves from a 200,000 mile car are generally, reusable. We've reinstalled the original OEM valves, minus two that were bent, in an engine with 610,000 miles. Now that engine has 735,000 miles and it still has the OEM original valves in the head. Valves are a case by case basis, but unless you are just anal, they DO NOT need replaced. Bent valves are BAD VALVES. Otherwise, we fit valve guides to valve stems.
200,000 miles means the cylinder head needs new valve guides. Our shop replaces them and we make them tight. We find the .051" rock measurement tolerance VW allows for stem/ valve clearance unrealistic. Concentrically cut valves to seats; dropping the valve straight into the seat is the art.
If someone is replacing all the valves, money is being spent unnecessarily. Knowing the difference what should or should not be replaced is being gentle to the customer's bank account. Also, there are few companies that make really good replacement valves. I'd rather keep a good, reusable OEM valves in the head.
