Putting new risers on and I'm trying to decide if I should go with the taller riser. It was recommended by Volvo to take the flappers out of the exhaust which I did but then to put on the taller risers. Which I didn't. I cant say that I've had water intrusion but I'd like to do what is recommended. The tall risers are 11.3 inches tall. From the top of my manifold to the engine compartment cover (fiberglass) it is 11.5 inches leaving me about .25 of an inch clearance. I know the risers get hot but if the water pump is working properly I can.put my hand on the top of the riser. My concern is doing damage to the compartment cover which I dont want to do. Also, if I have an impeller failure I afraid of catching fire. Any suggestions? Heat shield? Or is it not worth the risk. I'm not sure what the recommended clearance would be from the top of the riser to the engine compartment cover.
Thanks in advance.
