5SFE Valve Stem Seals help

I have a 95 Toyota Celica GT. 97k miles, 5-speed MT.
On every cold start up, there's a puff of blue smoke then everything is back to normal. (No blue smoke while driving).
This all leads to faulty valve stem oil seals.

I already bought the intake/exhaust valve stem seals.
Spark Plug seals and valve cover gasket.
Throttle body gasket.
all parts OEM.

What else would I need/recommended parts?
Intake manifold gasket?
EGR tube gasket?

If anyone knows a reputable shop with good prices, let me know for any around in the Los Angeles, CA area (90017)

Thank you.

You (or the mechanic you use) shouldn't have to remove the intake plenum to change stem seals unless it's modified. Get a tube of RTV (Permatex Ultra Grey unless you like Toyota's FIPG). Ultra Black and Ultra Copper work too.

You should reseal the semi-circular plugs and the distributor plug behind the coils. make sure the surfaces and clean and dry, because RTV doesn't stick well to oily surfaces unless you're using Permatex Ultra Blue. But I'd still clean them well.

Do you have the lever type spring compressor? I prefer the rope trick to hold the valves in case of power failure with an air compressor. Here are related discussions and similar DIYs below. If needed, you can also PM ToyotaPartsMan, he's a dealer parts manager in Newman Georgia and gives members 30% of msrp. Otherwise use Fel-Pro from local parts stores or rockauto.com.

While at it might as well check the valve clearances or even do a complete timing belt job. Borrow the large socket and a torque wrench from Autozone's free loaner program (with refundable deposit) if you don't already own them. Of course a decent mechanic should already have these. The shop may charge 5-6 hours of time if this includes the complete timing job using the following parts.

An example of a complete timing belt job can include:
GATES K030295 Micro-V AT Power Steering Belt $5.14
GATES K050435 Micro-V AT Alt/AC Belt $14.10
FEL-PRO TCS45920 Crankshaft Front Seal Set $5.10
FEL-PRO TCS45641 Camshaft Front Seal $3.66
NATIONAL 221820 Polyacrylate Oil Pump Shaft Seal $2.86
GATES TCK199 (1 Belt, 1 Tensioner, 1 Idler) Timing Belt Component Kit
$52.89
STANT 48278 180° w/Jiggle Pin OE Type Thermostat $10.94
AISIN WPT010A Water pump w/o housing $30.79
FEL-PRO VS50304R1 Valve Cover Gasket Set w/Spark plug tube seals
$18.26
Subtotal $143.74
Shipping about $20

You can add NGK wires and Iridium-IX spark plugs and radiator hoses too. etc etc

what other maintenance items need to be done? how is your clutch? what about the timing belt?

changing the valve stem seals with the engine in the car is not an easy job. the links posted above will help but personally when i do this job, i pull the engine and overhaul it. im a little quirky that way and go above and beyond. Ill replace the bearings, pistons rings, clean the engine bay really good, ill do it right so ill have no issues for another 100K miles.

Thanks for the input guys.

The only thing I've done so far is:

Replaced spark plugs with Denso platinum
Spark Wires with NGK
Distributor cap and rotor, Denso/OEM
Distributor oil seal, OEM
Thermostat and thermostat housing with seal, OEM.

I was planning to do the timing belt soon but I was stuck thinking what brand of parts I should go with; I'll just use JohnGD list.

None of the work will be done by me since I don't have the time and space.

I'm just in the verge thinking whether replacing the valve stem seals will be worth replacing or not.

Transmission wise, everything is fine. I don't think I'll need a clutch soon.
I only have about $1000 to spare
I don't think I have enough to pay a mechanic/parts for a engine overhaul.

You can also contact ToyotaPartsMan and get a quote of OEM parts and compare. (Send a private message, under "Contact Info" tab in the link below) http://www.toyotanation.com/forum/21...opartsman.html There are also discussions on what online dealers to use to buy parts.

The Aisin pump and Stant thermostat are made by OEM in the above list but don't carry the Toyota name. Besides the Toyota Red coolant (use with 50% distilled water), full-strength equivalent "Pentofrost A1" can be ordered at NAPA and O'Reilly. Or 50% pre-mixed Zerex Asian vehicles coolant about $14/gal at NAPA.

You can look up parts prices on rockauto.com and verify the application. Use the 5% discount code too. RockAuto Discount Code

Alright, I made up my mind.

I am just going to replace the timing belt and other components that go along.
I did a compression test today. Numbers are:
Cyl1: 190
Cyl2:192
Cyl3: 185
Cyl4: 190
That was a dry test. I didn't do a wet test.

I am just going to ignore the valve stem seals for now and just use the rest of my money to upgrade my suspension and other maintenance stuff I have left.
I noticed that for every oil change interval (3000 miles) I lose less than half a quart of oil. For now I am just going to keep using Castrol GTX high mileage and not worry about it....for now.

Thanks JohnGD for the timing list. It helped a lot.

your compression numbers are good. while you should do the timing belt if needed, you should reconsider the valve seals.
