hi a few month ago i engine over heated and i had to replace the head gasket, i dont know much about cars but i was told that something had to be taken apart 2 heads i was told something like that and then grinded and placed back...

 

what i would like to know is does this mean that engine will not perform the way it should does it loose power

 

is there anything that i can do today to improve the way the engine works

to improve the power of the car without any major cost

 

and can someone recommend what a good engine oil i should use at the moment it has 20/50, if i put new oil is there something i can put to clean the engine before putting new oil in

 

and one question how do i knwo if the gear is no good anymore what are symtoms to know i should change the gear

 

the car im talking about is subaru brat 1.6l 1993 manual

 

any tips on what should be done to bring the car back good working order is very aprecciated

 

thanks to all

a HG is the seal between the cyl head and the engine block. The HG keeps the cylinder (that has 160psi compression and 16,000 plus combustion pressure) the water channels and the oil gallies from mixing. The HG erodes with time due to repeated heating colloing of the block and may fail.

They took you head off and rebuilt it. This involves resurfacing (grinding) the valves, valve seats and knurling the guides. the last step stops oil burning. They also put on new valve stem seals. They check the heads for flatness and mil them so they are flat (they can warp). They check the springs and cams for wear.

This actually brings the top end of the engine back into like new condition. You will notice more power since you didnt buy it new. It is alos possible to have a very slight power increase due to the slightly higher compression from milling the heads.

Not much to imporove the way the engine works,

If the car has overheated change the oil. Go by whatever sooby recomneded for that year.

CHange the lubricants in the differnetials and transmission. The tranny may grind between shifts, especially the 2-3 shift, which is a weak spot in the tranny. Dont speed shift and you will be fine. Sometimes using redline oil will help it out.

Are you asking about the proper way to shift or when to replace the tranny? If its when to down shift, never let the engine chug or lug or strain, you must downshift. No falt answer on when the trany is scrap.

Are you having shifting problems? COuld be a clutch.

Hope that helps.

If this is a 1993 you may be better off in the new forum, or is it an 83? How many miles are on it.

/me points out to Nipper that the EA71 was produced well into the early 90s in other countries

 

He probably very well has a 1993 EA71 Brat.

nipper

well first of all thanks for the explanation !! i hope you mean transmission when you say tranny.

 

umm what is the diffrential and how do i replace the oil ?

 

once again thanks for the xplanation very aprecieated

 

any other tips perhaps as what i can do to cars engine or transmission to bring the car back some more power..

 

i dont expect the car to be more than what it is but for some reason i always feel that the car does not have enough power especially 2nd gear very week

 

week = doesnt pass 40 45 kmh usually i barley reach 40 and put in to 3rd

 

just feels weird aswell as i dont have a rpm clock so im not sure what rpm

im at but from the sound doesnt sound like i can pull any more and do all brat make alot of noise ?
