Mine had bubbling and pressure build-up when cold issues....

kapapalit ko lang ng HG the other day on my 4D56B turbo engine with the federal mogul brand.

so far it runs fine as of today. no bubbling and pressure build up when cold...

i followed the instructions provided by mechanics here in tsikot plus the instructions on the manual plus advice/tips from my mechanics-friends.

i torqued to 3 stages (4-8-12 kgm) with 10 minutes settling time between the 2nd and 3rd stages....ang hirap pala magbasa ng manual torque wrench while torquing the bolts lalo na sa 3rd stage...how i wish na may automatic torque wrench ako na ginamit..napakamahal kasi nun

di na rin ako naglagay ng shellac sa HG...just the gasket alone.

once kasi na nagoverheat ang aluminum cylinder heads eh hindi na yan titino unlike cast iron heads...aluminums loose their original strengths drastically after 1 overheating only
