7M had a blown headgasket...

[UTERUS]

I am upto the point where all i need to do is put oil in it and start it up.

Should i....

Take the sump off, clean it out and clean out the oil pickup?

Do something else i dont know about yet?


I have about 8 litres of new oil, 3 oil filters and 2 bottles of the engine flush stuff which you put in the oil before you drain it to clean it out.

Do i need to crank the motor over without firing it for a certain amount of time to get the oil pressure up?

Thanks!
Simon.

Use some cheap oil and filter for the first oil change and drive it for maybe an hour max. Then put in a bottle of engine flush and let it idle for 10~15 minutes (do NOT drive it with engine flush in it) and then drain all the oil out.

Now do the 2nd oil change with good oil and filter and you should be sorted.

[big_boy]

yes crank it with the ingction disconcted til the light goes out 1st & i would take the sump of & clean it but thats just me

[Punter]

I'd crank it with the spark plugs out, no load that way.
Though probably doesn't make much difference.

No need to remove sump

Make sure all the air breather pipes are clean (one behind alternator mainly)

Fill with cheap oil and run engine till warm for *&(^ sake dont drive untill running clean oil quality oil

Get her warm then drain and refill both water and oil pull off the lower rad house keep the antifrezze but fish out those bits of sand paper that would have killed your new water pump

Fill with new oil & new filter run till at normal temp THEN enjoy driving

anti-freeze can kill a new head gasket, so make sure you don't run any at first

[UTERUS]

Cheers guys, i will take all that into consideration

[Mr Revhead]

how can antifreeze kill a new head gasket?

[mr pad]

It can stop the gasket from setting correctly.

[Mr Revhead]

interesting that the only mention of that is on internet forums.
and not in any manufactors repair manuals.

Can't see how antifreeze could have any effect one whether or not the head gasket seals.

Perhaps one of the proponents of the burgeoning internet myth may care to explain.

[AE85coupe]

sorry its not an internet myth

i'm going off what a local engine reconditioner told me

so i guess its a local engine reconditioner myth?

Could be, I've never heard any engine reconditioner, or any mechanic, say that you shouldn't use antifreeze.

But you still haven't explained how it's possible for antifreeze to affect head gasket seal. I cannot see how antifreeze is even going to get between the mating surfaces of a properly prepared head and block.

I actually have no idea why

just going off what i was told

guess if i had the choice i would not run anti-freeze for a bit, better to be safe than sorry and all that

which is exactly how internet myths start

Which is why you should run antifreeze from the start, especially in an engine that has an iron block and aluminium head, avoid corrosion right from the start.

If it was such a problem then why do new engines come with antifreeze? Surely they would run them without it until the first service,. Also as Mr Revhead states why don't repair manuals say not to add antifreeze?

...just going off what a reputable qualified engine reconditioner told me

i'm not saying its right or wrong, i'm saying there is no harm in doing what he says

oh and i'm sure your engine is going to corrode away and do some serious damage for the short amount of time you would not run anti-freeze

[Mr Revhead]

every scratched a piece of aluminum and seen how long it takes to fade again?

[fivebob]

...just going off what a reputable qualified engine reconditioner told me

If hes so reputable and qualified then get him to explain why, and I don't mean saying that it stops the gasket from setting or some such other non explanation, I mean in terms of what the mechanism is that causes the issue.

i'm not saying its right or wrong, i'm saying there is no harm in doing what he says

If you don't know the why's of his recomendation, how do you know for sure it does no harm???

Ever heard of electrolysis between dissimilar metals?

Again I ask, why don't manufacturers, or for that matter publishers of repair manuals, state this to be the case. Without exception they say to use antifreeze.

[AE85coupe]

yes i know what alluminium is like? and i know anti-freeze is very important

[AE85coupe]

o.k, i'll ask him when he gets home

hey i'm really sorry, just trying to help the guy who made this thread

still can't see any harm in not running anti freeze for a short period, hell i've seen engines that have never run anti-freeze, they are corroded to hell, but they still function (toyota 4k's mainly haha)

and yes i know about electrolysis between dissimilar metals, you really are pathetically condescending
