Leakdown test service - Where and how much? or at least a compression test service.

[niky]

Ah. I've done that too. Painful. Cracked the cylinder head on my Sentra in a flood. We had an odd burp in the coolant temps after the overhaul that we couldn't trace... and that was the finding.

compression test, speedyfix, servitek or any decent shop. costs 200-500

leakdown test: machine shop. costs 3k-6k plus mechanic labor plus parts. usually sa overhaul ito

I went to speedyfix for a compression test. It cost me 200 pesos. The results were 120-120-70-80. Due na daw to for overhaul. I'm quite new when it comes to car, which is better in my case, top overhaul only or overall? I own a Nissan exalta sta.

with those numbers, loose compression na talaga. general na overhaul yan talaga.

since malaki din gastos mo, i suggest you consider getting a surplus engine

wet or dry compression? what was the reading after naglagay ng konting oil sa cylinders. nandun ang sagot kung overhaul or top overhaul lang.

Thanks for the input. So basically, konti lang ang difference ng gastos pag general overhaul and pag bumili ng surplus? Parang mas may advantage ang pag bili na lang ng surplus cause I do have plans of getting a stronger engine para mas gumanda ng konti ang takbo since I own a matic car.

I don't know kung what type ng compression check ang ginawa eh. Di din nilagyan ng oil yung cylinders. Yun lang yung reading na binigay sakin. Loss compression lang engine ko e, di naman nagbabawas ng langis masyado. Do you have figures sir ng rough estimate ng general overhaul?

when our corolla was overhauled in 09, around 40k din inabot. machine shop nagpamahal.

Should get a leakdown to determine why the compression in those two cylinders is low. It can basically pinpoint where the pressure is going, whether out the piston rings or through the head gasket.

Thanks for the input! I hope top overhaul will do. But I do have plans of upgrading my engine.

Dati low compression 4G13 engine ko at pinalitan ko ng 4G15 engine. Almost same lang result ng FC 6km/ltr. Hindi ko kasi pina overhaul yun nabili ko surplus na engine 4G15.
So, I end up na ako na mismo nag DIY rebulid ng 4G13 engine ko para sure ang pagkagawa at mas tipid pa. 12K gastos ko kasama na yun machine shop rebore at relining and parts at mounting ng 4G13 uli sa kotse ko. Almost 160 PSI result dry compression test ko sa mga cylinders ko. Hindi na masama sa first time engine rebuild ko.

Nakatabi na lang 4G15 engine ko ngayun at general cleaning ko uli lahat ng parts para benta ng chop chop.

If I were you. General overhaul mo na lang dating engine mo. Kasi yun surplus engine ay pa-overhaul mo para tipid ka sa gas and for better performance. Pwera pa dito yun sakit ng ulo at gastos ng pag change engine LTO.
