Not sure about frost plug but if you have a leak and you can't find in externally then could be in the heater core and going into the motor. Does your oil look like a chocolate shake? If not you may have a leak in the radiator but it is being burned off so you can't see it. Usually will leave white traces after heated and burned off.

Does a water pump gasket problem lead to other gasket problems- such as intake or head gaskets/ and is it associated with having coolant loss issues?

If the low coolant from the water pump leaking has caused the engine to overheat, then the cylinder head(s) can warp and the head gasket(s) will leak also.

Temperature gauge goes up and don when I am driving, but sits on halfway when my car is running and sitting still, what could be going on?

Have your coolant cap checked. If it is bad it won't hold pressure and it will allow coolant to leak out.

I was told i have a minor head gasket leak but i have not noticed any problems with its performance. how do i know if i should fix the 2 gaskets?

If you let a car run for a half hour, you can over heat &
ruin the exhaust converter.

There is a product called Combustion Leak Tester

It is a plastic tube the goes over the radiator or coolant
cap, in place of the cap & is filled with blue fluid,if it turns
yellow you have exhaust gases in the coolant,thus a head
gasket problem

A cylinder leak down test may be in order,certainly after
any repair or head work.

My 325i has been running at low coolant level

What you're describing is a blown head gasket or a cracked head. What's happening is the gasket or head is letting coolant get into the combustion chambers of the engine, producing your white smoke, and accounting for your coolant loss. You need to take it in to get checked out; often times if the head warped or something, it will need to be machined. This is something that's urgent; you can ruin your engine quickly running it this way. For future reference for you, here's the different smokes you will see and what causes them. White smoke-coolant in the combustion chambers, caused by leak in head or head gasket. Blue smoke-oil in combustion chambers, can be caused by worn, broken, or weakened piston rings, faulty PCV valve, worn valve guides. Black smoke-engine running too rich, and unburned fuel is escaping. I hope you get it fixed soon, those 3-series are great cars....mine's been awesome.

My 99 cadillac deville ran hot about 8 months ago i took it to the dealer thay told me that i need a new engine and to drive it for a couple days and see what happen i have been driving it for eight months...

If you have no obvious external coolant leaks then the most likely culprits would be leaking head gaskets or warped heads. I would take the car to an engine rebuilding shop and get a second opinion to the dealer, not to say that they are wrong, but your engine may be salvageable at a cheaper cost and those guys would be better positioned to tell you that. Hope this helps.

99 deville head gasket leak?

A head gasket leak is usually indicated (among other things) by continous overheating of the motor, and subsequent loss of coolant.
It can also be indicated by the presence of engine combustion gas bubbles in the coolant resevoir.
Ensure the coolant system has no external leaks, such as faulty hose/s, radiator etc.

Ensure motor tune or other motor mechanical condition is not the cause of overheating.
I assume the motor is actually running hot.

Check cooling fans are operating ok (as necessary when car warms up):- if not check
1) fuse,
2) relay operation,
3) heat sensor switch.

Check/replace the thermostat,
Check the coolant pressure cap is serviceable & of correct rating,
Ensure cooling system is correctly filled, bleed off any airlocks as necessary when re-filling,
Ensure radiator hose on suction side of waterpump is not collapsing at engine revs above idle (due softening),
If the motor has been severely overheated, the head gasket could be blown - look for combustion gas bubbles in the coolant resevoir.

Oil leaking into coolant system

OK this can be 2 things. Either a blown head gasket which can produce oil in your coolant and over heats the engine. The 2nd is less likely and that is that your radiator and oilcooler both are leaking.
My guess is the head gasket. Good luck this will cost you quite a bit.
