Overhauling Estimates - price check!

[xfreemanx]

Bad news for me. My 94 Corolla GLi needs an overhaul. Read the previous threads. The tell tale signs are there. Some smoke when I remove the valve cover cap and the oil dip stick. Some wet oil deposit on the tailpipe. A little bit more noisier than usual.

So I got an estimate from a shop the sells the parts and has a machine shop and inhouse mechanic along Proj 6 QC. I asked for their best price for parts and machine shop services, for the benefit of fellow tsikoteers na din.

PARTS
Overhaul Kit - 1650 Federal
Master Bearing -750 Taiho brand
C Rod Bearing - 450 Taiho
Valves - 1900 Fuji
Piston Ring - 950 NPR
Thrust washer - 280
Motor Oil - 480
Oil filter - 190
Spark Plugs - 600
Timing belt - 1680 toyota
Paint thinner - 200
Rags - 60
Silicon x 2 - 190

If engine is really bad:
Liner - 1700
Piston - 1800
TOTAL: 12610

MACHINING 16 Valve 4aFE
Resleeve - 1800
Rebore - 2800
Polish - 800
Fitting - 900
Regrind - 1800
Oil Seal Build up x 2 - 1200
Valve Seat and retappet - 4500
Washing - 400
TOTAL: 14200

Whew! Magastos pala. Di ko pa pinapagawa.

Do you think the quote is fair enough? Which of the Machining services are essential and which are optional? How do I know if I need to have them done on the engine?


Gurus, pa-advise at paexplain naman! HELP!

ganun talaga sir... sa mga gasket po nya mas maganda kung original parts po ilalagay... pero ok na din po yan

What are the causes ba para ma overhaul ang auto? Age lang? Yung 96 GLi ko almost 50k ang quote for full overhaul pero sa top of the line na pagawaan yun (specializing in Toyota). Mahusay kausap yung may ari. Buti na lang false alarm at hindi pa kailangan ng overhaul. wheeeew.

wala ako nakita LABOR charge

magkano labor?

mam.. loss of compression, blowby and engine knock..

OT but what would cause that? Normal wear and tear? Basta ba change oil religiously hindi yan mangyayari o hindi maiiwasan basta luma na car?

Parang ang hassle mag overhaul, option ba magpalit na lang ng engine?

[Geo B Santiago]

hi! Puwede ring option ang magpalit ng engine. Halos ganun dis ang gastos. That is according to my mechanic.

[technismo]

yah tama mas ok pa nga yun magpalit ng engine... hindi talaga maiiwasan yun darating din yung time nya mag overhaul.. wear n tear tlga ang engine .. hehe

[speedyfix]

that's pretty cheap na. if you trust that they can do the work well then ok na yan.

Thanks for all your inputs! I think the shop owner is trustworthy. He guarantees the work for 6 months, and labor is 4K.

For the machining, how do I know if my engine needs them? Para saan ba to?
Resleeve - 1800
Rebore - 2800
Polish - 800
Fitting - 900
Regrind - 1800
Oil Seal Build up x 2 - 1200
Valve Seat and retappet - 4500
Washing - 400

These are needed for a complete overhaul. My dad told me that it's more advisable to do a complete overhaul (than a top overhaul) as the engine will receive more fresh parts thus, will generally last longer. On the contrary, a top overhaul will cost less but may give more headaches in the future.

As far as I know:

Resleeve-replaces the cylinder wall with a new one.
Rebore-resizes the cylinder wall to make a perfect fit for the new pistons.
Polish-polishes the cylinder head to improve or restore intake/exhaust performance

Thanks for your very informative posts bros. It really helps. Will be bringing the car tomorrow. Had canvassed for surplus engines at banawe, price is 20-25 din, japan local version daw. But I figured, the expenses will be more expensive if I swap the engine. Rewiring and installation plus having the engine reconditioned too will mean more pesoses out of my pocket.

So pag rebore, no need to resleeve? Does it need to be polished pa?

How about valve seat and retappet? When do I need this? And what are the specs for the clearances?

Hmmm, I have no idea if all cars need a resleeve when overhauled. I just know that my dad used to do it in VW Old Beetles back when he was in college. But in modern cars, nada. But I do know that a rebore is needed in an overhaul. Polishing on the other hand, is done on the cylinder head. It ensures good flow of the fuel/air mix on the intake and gases on the exhaust. As for valve seat and retappet, I only know that it concerns the valvetrain. AFAIK, this is to recondition the valvetrain to compensate for wear and tear. Lolo told me that inspection of valve clearance is routine maintenance procedure.

Nakuha ko na yung oto. Engine is less noisy and no more smoke coming out of the dipstick. I paid a total of 29K, 11K for machine shop, 14K for parts and 4K for Labor. I am hopeful they did a good job. Malaking gastos e.

[banawe]

the price of the parts looks fair enough ...

the machine shop is a bit taga if you ask me ...

the labor i think is about 3000 - 3500 lang

if you like to canvass give me a call i will try to give you a great deal sa price

4000 to pull down the engine and overhaul it is expensive?
