Okay, we all know a vaccum test is a critical step in the rebuilding process...a bad seal can fry yer top-end...but most of us don't have the fancy factory jigs and fixtures for covering the exhaust and intake ports for the test...
Here's the lazy way...and there's nuthin' quicker!
There are special tapes made for waterproofing...the one i use is called "Eternabond", and it's made by the Vaproshield company (you can look 'em up on the internet, and find a local supplier or order on-line)
The tape is thick and super-sticky...it's a "peel and stick" with a special clear release liner. You cut small square sections for your ports, and just peel and stick them on...this stuff REALLY bonds well. Then just use the impulse line hooked up to your vacuum gauge to run yer test...the tape will easily hold.
Best of all...it will peel right off after the test, and not leave any residue...no mess to clean up at all...
Don't try this with duct tape, packing tape, masking tape, etc...IT WON'T WORK! Only these heavy waterproofing tapes will do the job. Plus you will probably find lots of other uses for this kinda tape...it's like duct tape on steroids...i have even fixed leaking pipes with it.
Here's a 200T under test...It fell 50 feet outta a tree...the seals were still good, but can't say the same for the handle, fuel tank, bushings, etc...
