I have a Volkswagen beetle 2.0 engine. When I take the oil cap off it has
some yellow just like you showed in the video. But when I use the oil stick
to see how much oil I put into the engine. I don't see any yellow color
just clear like the synthetic oil. On the other hand my car ticks and when
I drive it seems to cut out between shifting gears like I have it in the
wrong gear. I know how to drive a stick Ive had the car for about 7 years
it has 151,000 miles on it. Could this have any part of a bad head gasket?

@DARIUSSR612 You may not have a thermostat opening, or fans may not be
coming on or a bad fan clutch. Also stop leak products can plug up your
radiator and make it run hot.

Author briansmobile1 (2 years)
@DARIUSSR612 If you have a new waterpump, t-stat, no leaks, full of
coolant, fans work, and radiator cap is good- then you've likely got a
plugged up radiator or air is blocked from getting to it- or your head
gasket is bad.

I got a question, I have a 1994 Caprice LT1. My Oil always looks clean, I
drained the antifreeze before, no oil. From the right side of the motor,
there is a constant chat, chat, chat, chat, chat noise. I recently had my
exhaust rebuilt (for multiple holes) & a new Exhaust manifold gasket on
that side. I want to check for combustion, but if I put on a new head
gasket, and that noise is still there, how do I know if my heads are bad
and they need to be re-worked?

Author briansmobile1 (3 years)
@najju07 I recommend NOT using additives ambiguously upon suspicion and not
at all unless the cars value is less than the cost of repair (totaled).
Your best bet is to fill the radiator full of coolant and let it warm up at
idle with the hood open and watch for where the coolant comes from. Then
replace or repair only what's broken. If you use a sealant short cut it
WILL plug up things you don't want plugged.

@MrStraightProduction Rusted away water pump fins or a bad thermostat, or a
bad fan clutch.

Author briansmobile1 (3 years)
@sohail786 First make sure there's plenty of coolant in the radiator when
it's cold. Then warm up the engine. Check for leaks when it's warmed up.
Air gets trapped in the heater core first when coolant level is in decline.
Poor heat delivery can be from a thermostat that is stuck open, air in the
heater core, or corrosion sludge blocking the heater core. That last one
you can check for by warming up the car and grabbing the heater hoses that
go into the firewall. If one's hot and one's not.

Hi, is there any other reason for having this mixture in the radiator than
a blown head gasket, I found this mixture after a very small heating and I
have changed all my head gaskets set and the oil continues going to my
radiator, I have a lot of oil inthe radiator, but nothing of water on the
oil. Parts for my car are really hard and expensive in my country i want to
check for another reassons before having them change again.

Author BmxDieseldude (3 years)
@sohail786 this could be a radiator leak, but could also be the heater
core, or any of the lines. if you start to lose heat, as the engine begins
to get hotter, odds are you're getting air into the cooling system (air
replacing leaked fluid) and so the pump isn't pumping the coolant. i'd
guess heater core before radiator. what section of the country are you in.
a failed heater core can be bypassed easily if you don't need heat in the

Your engine head may be warped which prevents a proper seal.

i noticed my car recently over heat once, it went up to the max then it
dropped back down. i put some fluids in the resevoir and radiator then it
did not overheat again, but the reservoir started to boil after idle. so i
took it to a shop and they didnt say much, took it to another shop they say
leaking head gasket from behind, didnt believe it took it elsehwere and
they said sticking thermostat and bad rad cap.fixed it flushed rad also.
car is doing fine now but should i be woried? respond asap

I think I just blew the head gasket In my 1990 Toyota Supra N/A. I did a
radiator flush, then the next day I did an oil change...that night I was
drving home, and the temp gauge was almost at H, as soon as I noticed It I
turned off the engine, put it in nuetral and got to the side of the road. I
do have a little white steam from the exhaust, and It idle's weird, and Im
losing a lot of water/coolant. 2 shops have turned down the job so far.
Luckily my work Is only 10mins away. fml.

Author briansmobile1 (2 years)
@tompwh Runny oil could just mean it's a low weight oil. Bubbles in the
reservoir could be the result of a coolant leak creating excess air and
therefore steam to be pressing out. One of the best tests is to see if
there are compression gasses in the radiator. You can buy/rent a kit for
this at Autozone.

appreciated! thanks!

Author briansmobile1 (3 years)
@streetlimitz89 A little is normal. This is in Utah where humidity is near
zero all the time (desert climate). Also when you pull the oil drain plug
and find coolant.... it's a head gasket failure.

Author briansmobile1 (3 years)
@undergroundpredator Sounds like a lifter problem. I'm not familiar with
the caprice specifically, but if the push rods plug up they dont get oil
and can wear down and make not only the noise, but cause the valves to not
open enough to give full power. Hydraulic lifters can get stuck or sticky
and do the same thing.
