30 year old hoses....

Hey everyone...I have not posted in a long time, but now I have something to say. I'm in a 72 240z with an L.28, dual SU's and all kinds of fuxed up modifications. You would think if someone was going to do that kind of swap, that they might replace a lot of the rubber hoses that came on the car originally, right? Well whoever did it to my car didn't do that. I was driving in L.A. on the 405 to the valley, which anyone from L.A. knows is a long, slow climb until the final up-hill, which can be very strenuous on any car. Especially mine, because one of those 30year old hoses split and sprayed coolant all over the inside of my engine compartment. The dizzy is all wet, the coil is all wet, but thank god I don't have EFI, because I would have been fucxed. I let the thing sit in the valley for a day, to dry, and go to try and start it. No go. Coolant gummed up the carbs completely. I clean out the carbs, and I get a really, really rough time starting it, but it does eventully fire. The Idle is now all rough, and it takes a very long time to warm up. I filled up the coolant reservoir, but it still takes a long ass time to get warm. Like twice as long as it took before the hose split. It has been 4 days since the hose went, so I would guess everything is dry by now, right? what might be causing my sloppy starts, and terrible idle?

Dry under that cap!

I Do hope you removed your distributor cap and dryed out in inside with a kleenex or paper towel. Replace ever hose on your car that isn't newish. Norm K.
Maybe a faulty thermostat caused the hose to blow. Antifreeze should be wiped out of the distributor with a paper towel. It won't dry out by itself.
Replace the dist. cap and rotor. If the inside got wet when the car was running then the cap and rotor could be screwed. When you do replace them make sure that every thing is dry before you start it up. Change the points too or better yet (if it is not already done) switch to electronic ignition.
thank you everybody.
hey! i had a service manager(toyota)who never belived in changing the "origional" hoses either.....i guess he was never taught (like i was)that hoses rot from the inside out and need to be replaced every so often..
p.s. i'm sorta kinda in your neighborhood if you need a hand with the car.
I'm a believer in changing hoses. When I got the -Z- I have now, thats one of the first things I did. The L series of engines has an aluminum head, so you really don't want to overheat them. I look at new hoses as cheap insurance.
