Being off work leaves me filled with boredom so today I decided to make a boost leak tester since I'm still waiting for a new oil pan for my SR. Should cost you about 10 bucks if you already have a compressor. All stuff purchased at home depot.I found 4 leaks with this thing hahah.
Supplies needed to make said boost leak tester:
1)2 inch PVC CAP
2)1/4" compressor fitting
3)1/4" T-fitting
4)1/4" Pressure Gauge(not needed and totally useless LOL)
5)1/4" Air valve(required)regulates air flow
6)Working boost gauge (required)
7)Compressor(any one will do)
8)1/2" drill bit
9)drill
10)teflon tape(for fittings)
11)PVC cement (to seal the fitting on the cap)
To assemble drill a hole on top part of the cap then just thread the T-fitting on.There will be no need for a tap because the fitting will make its own threads as you twist it on.After you have threaded the fitting on remove it and dab some PVC cement on the fitting and use a cue tip to spread some cement on the hole you drilled on the cap.Twist the T-fitting and allow for 2 hours to fully cure then have at it.Apply Teflon tape to the other fittings then twist them on.
Step 1)Remove maf and install boost leak tester in place of maf.
Step 2)remove and plug nipple for the crankcase breathing system
Step 3)pinch or plug the vac line to the fuel pressure regulator
Step 4)recirculate or block off atmospheric dumped BOV's for testing purposes
Step 5)hook up air hose leave valve on tester closed
Step 6)turn compressor on and set the regulator to 20 psi
Step 7)slowly open the valve on the tester and charge up the system to 10 psi via using your boost gauge.
Step 8)Walk around the engine bay and listen for leaks feel around the couplers if needed.
Step 9)Fasten clamps zip tie vacuum hoses
