Engine question

[seadog30]

"Vibration dampers to bulkhead in cars"? Tell me of one. What is "displacing of a car engine" never heard the term in a lifetime of living with the garage business.

On the mini an "engine steady bar" was a standard fitting and when tuning for competition it was / is important to upgrade the steady bar bushes with a more sustantial fitting to reduce engine movement or displacement.

Lots of front to back inline engines i.e. Escorts also were fitted with steady bars to a strong point at the side of the engine compartment to damp engine movement.

As car engines now tend to run with less vibration the use of an extra steady bar is not so common now and will only be found on performance tuned cars, so they would not be seen by the garage fitter.

Quite, remember the Escort Mexico - and others around that time they had a bar across the engine bay to provide some addition stiffness. Not so noticeable on modern cars I think because body shells generally are now much stronger. A "test" we would carry out was to corner as fast as possible and put your fingers into the joint at the top of the door, in my "modern" Volvo nothing much happens, in a MK1 Escort your hand would disappear . .. . . . The even older Vauxhaul 101 was a bit bendy, with three stout guys in the back seat the floor pan would bow and hit the propshaft - those were the days . . .

An interesting post for me.... Seven years ago, I installed a Volvo D30 to replace the old, dead MD2B, and being broke, asked the Volvo agents not to replace the original exhaust. Last winter, on a new berth, waves forced water into the cylinder and I'm now looking at a serious rebuild on what is a new engine... Seriously unhappy. Of course, the agents don't want to know, but surely they might at least have been expected to tell me that a new exhaust with a better water trap might be advisable... As far as I was concerned, I was merely replacing like for like.

Sorry to hear of your woes but if it's any consolation, and assuming waves stern-on were forcing water past the swan-neck, a bigger water trap quite possibly wouldn't have made much difference -- although it just might have delayed the inevitable until you spotted it and took remedial action. (My sympathy is heartfelt, since I'm currently replacing an engine with terminal seawater damage.)

Unfortunately the old MD2B was a big big lump and the new engines are wee toys....Many do not realise the difference this few inches in relation to waterline height might make....The Beta high rise elbow helps remove this risk

In your boat it could have made the difference between the wave induced waters running in and then running out again with the old engine and just running all the way into the new engine with a lower height. It installers often ignore this!

Thanks for your concern, Bilgediver, but worry not: high-rise exhaust elbow & anti-siphon is part of the spec.

I'm sure you're right, but I would have expected the biggest Volvo agents in the region to have been rather more aware of the problem than I!
