Re: volvo aq170a press test

I didnt see anything dripping from the pump,i will recheck it closer will if be to the outside if it is leaking at the seals? Also would it leak oip out if the seals were bad on it?

Usually if the seals are leaking, it will drip out of the weep hole between the two shaft seals (bottom of the exterior of the pump) into the bilge. That's not to say that the weep hole may have been restricted with a unknown or known (someone trying to plug the leak) foreign object which could stop it from dripping, and possibly force water past the seals. Like I said, this is a long shot. The 170A/B/C/D engines are not cool customers when they overheat. An overheat usually will warp the head. And the heads are prone to cracks.

I think i am going to do a compression test first, i did one in the spring but it might help before i pull it apart. Ill let u know what happens .

Re: volvo aq170a press test

Well after the heat wave left and the A/C fixed on the truck. Well last weekend I pulled the head dropped it at the machine shop and got bad news back that its cracked in cyl #2. I took the exhaust manifold off and looked into to to find the 2 passages from and too the engine were pretty plugged with rust and crud. I put the hose to it and got it flushed out. I found the water flows into the engine on the port side ( near the engine) and from on the outside of the manifold or starboard side. Also look for stuff in the water passages around the cylinders in the block, mine had crud also. So now I gotta find a head, but if one isn't located I am told a place in IA. can fix my old one but they aren't cheap. Can I go with a different motor, say 8 cyl on the 270 out-drive?

unless the boat has a lot of sentimental value, I'd start shopping for something else, just my opinion.
