You have a leak - Check all your hoses and replace as needed. Any of them feel soft replace them and probably wouldn't hurt to replace the clamps as well especially if they are the manufactures clamps - Those only last for a few years.

87 Chevy pickup 305 has very high idle but runs great other than that. I've try tuning it down by turning the distributor had it sounding nice but no power on take off any thoughts

With the later model cars and trucks that are computer controlled, fast idles often means that there is some sort of vacuum leak in the intake side of the engine. Turning the distributor will slow the idle, but it also changes the engine timing, and this will result in the loss of power you are experiencing. The catch-22 of this is that now, until you can find and fix the source of the intake leak, you won't be ale to effectively reset the timing to the correct position.

Crankcase pressure

At IDLE the PCV does not open very much and therefore there may not be a vacuum under the valve cover.. maybe a couple psi. Try holding your hand over it and increase the idle? Does the air stop or reverse? (as you increase engine speed, the vac in the intake manifold increases and opens the PCV more so it will pull more gases out.) If so, I'm thinking you're OK. If your rings were really bad and you were getting lots of blow by you'd probably be seeing a Check Engine light (and other problems), and the air coming out would have smoke/oil vapor in it. No oil in the air cleaner? If 'no', then again, probably not excessive blowby. If I get a chance tomorrow, I'll check mine and get back to you how much is coming out of mine. Is it running OK otherwise?

Why on my1997tahoe when you remove the oil filler cap truck will stall and lots of suction

Well -doing that sort of takes out the PCV System
doesn't it

Unmetered air comes in the oil fill hole & gets drawn into
the intake & leans out the fuel mix

You also got PCV system issues with high vacuum

98 GMC 5.7L high idle and strong suction on oil filler cap

High idle usually indicates a vacuum leak, you may have one of the smog hoses disconnected, that would also cause a suction at the filler cap because the engine is taking in air pretty fast. I have a 93 2.8l and it will run fast idle for a short time when starting it cold, I have learned that is because it is running rich at that time and the computer thins a rich condition with more air so it is not smoggy.

Unless your throttle linkage is hung up, it is vacuum leak.

Where is the engine oil spout for a 1996 Chevrolet Blazer Where do you put the engine oil in?

depends on engine, some are on one or the other valve cover,my older GMC pickup( 305 v8), has it on the left valve cover toward frount, and says "oill here"
I have also seen older modles have a tube with a cap at midle frount of engine, usually it will be marked with either "oill here", or just plain "oill"
I hope this wil help!

I want to know the point to re-fill gear oil in my car

How to check & re-fill gear oil in automatic transmission on 1996 Audi A4:

At the bottom of the automatic gearbox (tiptronic) you will find 2 threaded plugs on below surface. First (in front of the car) is for emptying, and second is for filling up. Tightening torque is 24 Nm.


Automatic Transmission Fluid (ATF) checking:
1. Requirements for check:
1.1. Vehicle standing on level surface.
1.2. Transmission must not be in fail-safe mode.
1.3. Shift lever in "P" position, parking brake applied.
1.4. Engine idling.
1.5. Air Conditioner and heater OFF.
1.6. ATF temperature must not exceed 104 Fahrenheit degree (40 Celsius degree) at start of test.
1.7. Only ATF with designation ESSO LT 71 141 may be used. Do not use any lubricant additives.
1.8. Automatic Transmission Fluid ATF - part number: G 052 162 A2 (1 liter wrapping)
1.9. An ATF level check when transmission oil temperature is too low results in overfilling, when too high results in underfilling.
2. CAUTION: Too much or too little ATF will affect the operation of the transmission. The ATF level must be checked at regular intervals.
3. The oil level is correct if a slight amount of oil runs out when ATF temperature is between 86 Fahrenheit degree (30 Celsius degree) and 113 F deg (45 C deg) (caused by increase of oil level when heated). For warmer climates, 122 F deg (50 C deg).
4. Hang filled ATF reservoir VAG 1924 as high as possible.
5. Shift lever in "P" position, engine running at idle.
6. Place oil drip pan under transmission oil pan.
7. Remove ATF filler plug (at the bottom of the automatic gearbox you will find 2 threaded plugs on below surface. First (in front of the car) is for emptying, and second is for filling up.
8. With ATF temperature between 86 Fahrenheit degree (30 Celsius degree) and 113 F deg (45 C deg), for warmer climates, 122 F deg (50 C deg), a slight amount of oil will flow from filler hole when ATF level is correct.
9. If necessary drain or top off ATF to attain correct oil level. Top ATF with filler hook from VAG 1924 ATF reservoir. Insert VAG 1924 (tool) ATF reservoir filler hook into filler hole and top off until a slight amount of oil flows from filler hole.
NOTE: Fit filler hook into one of the oil deflector cap slots placed on the filler opening.
CAUTION: Do not press filler hook upward or oil deflector cap can be pushed off.
10. Reinstall ATF filler plug. Tightening torque is 24 Nm.

How do i inject the transmission fluid in the transmission

there is a small filler neck in frt. of the trany , with red cap on it. Brake the cap , there will be a plug under.
Proccedure : engine on idle , take of plug at the bottom of trany oil pan(with engine on idle!!!!! , if engine off , fluid will leak out) , use transfering pump to pump oil in to filler neck untill it starts leaking from bottom plug , wiat till it only drips , put bottom plug back in and torque it. Now you can shut engine off and seal filler neck.
Use only approved trany fluid .This trany takes syntetic fluid.

Engine speed drop

That is normal, when the oil cap is dropped the vacuum to the engine drops also cause the idle air valve to close due to lack of vacuum.
